Certified dimensions furnished upon request.HUB HUBBalance ConditionThese couplings are designed with a high inherent balance, due to the precision of the manufacturing process. It is important that all parts are carefully stored and fitted to maintain this integrity.The inherent balance of the T Series meets AGMA standard 9000-D11 class 9. The adjacent chart relates the T series rating to operating speeds on the basis of the AGMA class 9 characteristic to provide a general guide to determine if dynamic balance improvement is necessary.When balancing improvement is requested, John Crane will dynamically balance the transmission unit. Hubs may also be dynamically balanced, and this will be carried out after machining the bore but before cutting single keyways.Correct alignment of shafts is essential for reliable machinery performance.The angular and axial restoring forces in the table below are given at maximum deflections. The chart can be used to determine forces across the full deflection range. The nonlinear characteristics of axial stiffnesscan dampen a system to prevent high-amplitude axial vibration.Notes:1. Meets NEMA end float specification without modification.2. Maximum angular misalignment will reduce with rotational velocity in excess of 3600 rpm (only on sizes 0500 to 1400).3. Maximum angular misalignment will be 50% at the maximum axial, and vice-versa.4. V alues based on preferred min DBSE and maximum angular misalignment. Greeter parallel offset is achievable by increasing the DBSE.5. The coupling sizes shaded are non-preferred, and TLK couplings should be selected whenever possible.If the products featured will be used in a potentially dangerous and/or hazardous process, your John Crane representative should be consulted prior to their selection and use. In the interest of continuous development, John Crane Companies reserve the right to alter designs and specifications without prior notice.

online 28May 2008Keywords:Photo-Fenton PolyacrylamideFe(III)–SiO 2catalystHeterogeneous catalysisa b s t r a c tThis article presents preparation,characterization and evaluation of heterogeneous Fe(III)–SiO 2catalysts for the photo-Fenton degradation of polyacrylamide (PAM)in aqueous solution.Fe(III)–SiO 2catalysts are prepared by impregnation method with two iron salts as precursors,namely Fe(NO 3)3and FeSO 4,and are characterized by Brunauer–Emmett–Teller (BET),X-ray diffraction (XRD)and X-ray photoelectron spectroscopy (XPS)methods.The irradiated Fe(III)–SiO 2is complexed with 1,10-phenanthroline,then is measured by UV–vis-diffuse reflectance spectroscopy (UV–vis-DRS)and XPS to confirm the oxidation state of Fe in solid state.By investigating the photo-Fenton degradation of PAM in aqueous solution,the results indicate that Fe(III)–SiO 2catalysts exhibit an excellent photocatalytic activity in the degradation of PAM.Moreover,the precursor species and the OH −/Fe mole ratio affect the photocatalytic activity of Fe(III)–SiO 2catalysts to a certain extent.Finally,the amount of Fe ions leaching from the Fe(III)–SiO 2catalysts is much low.©2008Elsevier B.V.All rights

processes in China,a kind of new produced water containing polyacrylamide (PAM),a high molecular weight polymer,have been produced.The conventional method to dispose of such produced water is either re-injected into the subsurface for permanent disposal or discharged directly to the marine environment.However,both methods have caused serious contamination to the ground water and surface water.On the other hand,the current physical treatment processes (settling separation and filtration)can not satisfy the treatment requirement.Hence,the treatment technologies of produced water containing PAM have become a key problem in oil industry in China.Physical [1,2],biological [3,4]and chemical methods [5]are presently used for treatment of PAM.It was found that the degrada-tion ratio of PAM in aqueous solution was slow by using biological methods.Recently,some investigators have reported the successful application of advanced oxidation processes for PAM degradation [6,7].One of advanced oxidation processes,Fenton (a powerful source of oxidative HO •generated from H 2O 2in the presence of Fe 2+ions)or photo-Fenton reaction has been used in the degradation of∗Corresponding

compounds,it should be pointed out that there is a major drawback because the post-treatment of Fe sludge is an expensive process.This short-coming can be overcome by using heterogeneous photo-Fenton reaction.Therefore,a lot of effort has been made in developing heterogeneous photo-Fenton catalysts.For example,Parra et al.pre-pared Nafion/Fe structured membrane catalyst and used it in the photo-assisted immobilized Fenton degradation of 4-chorophenol [10].However,Nafion/Fe structured membrane catalyst is much expensive for practical use.Thus,the low cost supports such as the C structured fabric [11,12],activated carbon [13],mesoporous silica SBA-15[14–16],zeolite [17,18]and clay [19–21],have been used for the immobilization of active iron species.Remirez et al.prepared the catalysts using four iron salts as precursors for the heteroge-neous Fenton-like oxidation of Orange II solutions [22].The results showed that the nature of the iron salt had a significant effect on the process performance.So,it is necessary to discuss the photo-catalytic activities of the catalysts by using different iron salts as precursors.In this paper,a series of Fe(III)–SiO 2catalysts were prepared at different OH −/Fe mole ratio and by using two iron salts as precur-sors,namely Fe(NO 3)3and FeSO 4.All catalysts were characterized by BET,XRD and XPS.The oxidation state of Fe in the solid state was detected by the UV–vis-DRS and XPS measurement.The pho-tocatalytic activity of Fe(III)–SiO 2catalyst was evaluated in the photo-assisted Fenton degradation of PAM in aqueous solution

at an initial solution pH of 6.8.The effects of the precursor species and the OH −/Fe mole ratio on the photocatalytic activities of Fe(III)–SiO 2catalysts were also stud-ied.In addition,the leaching behavior of Fe from the catalyst surface was discussed.2.Experimental 2.1.MaterialsThe analytical grade PAM,H 2O 2(30%,w/w),Fe(NO 3)3·9H 2O,FeSO 4·7H 2O,NaOH and 1,10-phenanthroline were used for this experiment without further purification.The average molecular weight of PAM was 5000000Da and degree of hydrolysis of PAM was about 30%.Silica gel (40–60mesh)as a support was purchased from Qingdao Ocean Chemical Company,China.The aqueous solu-tion of PAM was prepared by dissolving a weighed quantity of PAM in distilled water.2.2.Preparation of the catalystsA series of catalysts were prepared by two methods as follows:(1)Two catalysts were prepared by impregnation of 20g silicagel in aqueous solution containing 0.05mol/L Fe(NO 3)3and 0.05mol/L FeSO 4,respectively and kept stirring for 6h.After aging for 40h at 105◦C,the samples were separated and washed several times with deionized water,then dried overnight at 80◦C.The dried samples were calcined at 500◦C for 5h in an oven.Finally,two Fe(III)–SiO 2catalysts were obtained,namely S-Fe 3+and S-Fe 2+.(2)Twenty grams of silica gel carrier were first added into the aque-ous solution containing 0.05mol/L Fe(NO 3)3and 0.05mol/L FeSO 4,respectively and kept under vigorous stirring for 2h.Then,NaOH aqueous solution with different concentration was added drop by drop under stirring until the OH −/Fe 3+or OH −/Fe 2+mole ratio was equal to 1and 2.After aging for 40h at 105◦C,the solid product were separated and washed several times with deionized water and dried overnight at 80◦C.The dried samples were calcined at 500◦C for 5h in an oven and the catalysts were named as S-Fe 3+/1,S-Fe 3+/2,S-Fe 2+/1and S-Fe 2+/2,respectively.2.3.Characterization of the catalystsThe iron content of Fe(III)–SiO 2catalysts were verified by an inductively coupled plasma (ICP)(Model:Perkin-Elmer 5300DV)after acidic digestion of the catalysts.Brunauer–Emmett–Teller (BET)specific surface area,total pore volume and average pore size of synthesized Fe(III)–SiO 2catalysts were measured by adsorption of nitrogen at 77K,by using auto-mated volumetric adsorption instrument (model Quantachrome Autosorb-1).X-ray diffraction (XRD)measurement was employed using a Rigaku D/max-rB system with Cu K ␣radiation operating at 45kV and 40mA.The 2Âranged from 10to 90◦.X-ray photo-electron spectroscopy (XPS)measurements were performed using a PHI 5700spectrometer.The X-ray source was operated at 250W and 12.5kV and the C 1s signal was adjusted to 284.62eV as the reference.The curve fitting was achieved by using a Physical Electronics PC-ACCESSESCA-V6.0E program with a Gaussian–Lorentzian sum function.Finally,UV–vis-diffuse reflectance spectroscopy (UV–vis-DRS)measurements were recorded on TU1901with a sphere reflectanceaccessory.Fig.1.Schematic diagram of three-phase fluidized bed photoreactor.2.4.Catalytic activityThe photocatalytic activities of Fe(III)–SiO 2catalysts were evaluated by degradation of PAM from aqueous solutions in a three-phase fluidized bed photoreactor (Fig.1).The light source was UV lamp (Philips,8W,254nm)fixed inside of a cylindrical quartz tube.The total volume of PAM aqueous solution was 1500mL.In order to ensure a good dispersion of Fe(III)–SiO 2catalysts and good mix-ture in solution,compressed air was bubbled from the bottom at a flow rate of 3.3L/min.For each experiment,the concentration of PAM and H 2O 2were 100and 200mg/L,respectively.The cata-lyst loading was fixed at 1.0g/L.The Fe(III)–SiO 2catalyst and H 2O 2were added into the photoreactor,at the same time,UV light was turned on and this was considered as the initial time for reaction.Then,samples were withdrawn at time intervals.The concentration of PAM in solution was measured by starch-CdI 2spectrophotom-etry [23].To determine mineralization of PAM solution,the total organic carbon (TOC)of the reaction solution was measured by a TOC-V CPN Shimadzu TOC analyzer.In addition,the concentration of Fe in reaction solution was monitored by ICP.2.5.Characterization of Fe(III)–SiO 2after the reactionIn order to know the oxidation state of Fe on Fe(III)–SiO 2catalyst surface under irradiation,the 1,10-phenanthroline was used which would be complexed with Fe(II)–SiO 2in solid state [17].0.03%1,10-phenanthroline and 0.6mol/L acetate buffer (pH 8.60)was added into the photoreactor and the S-Fe 2+/1catalyst was irradiated for 2h.After reaction,the sample was filtered,washed several times and dried,then characterized by UV–vis-DRS and XPS measure-ment.3.Results and discussion3.1.Characterization of the catalysts before reactionThe content of Fe in Fe(III)–SiO 2catalysts is shown in Table 1.It is observed that the Fe content in catalysts increases with the increase of OH −/Fe mole ratio in both Fe(NO 3)3and FeSO 4used as precursor.It should be mentioned that,with the increase of OH −/Fe mole ratio,the structure of iron species in the solution develops from the low-molecular-weight species into high polymerization degree cationic polymer [24].Therefore,with the increase of OH −/Fe mole ratio,862T.Liu et al./Journal of Hazardous Materials 162(2009)860–865Table 1The content of Fe in catalysts and the results of BET tests Samples The content of Fe (wt.%)BET surface area (m 2/g)Total porevolume (cm 3/g)Average porewidth (˚A)SiO

polymerization degree of iron which was absorbed on SiO 2car-rier increased.It indicates that increasing OH −concentration can improve the loading of Fe in Fe(III)–SiO 2catalyst.The BET surface area,total pore volume and average pore width of the investigated Fe(III)–SiO 2catalysts are also listed in Table 1.The surface area of S-Fe 3+and S-Fe 2+catalysts were 446.0and 442.6m 2/g,respectively,higher than the SiO 2carrier.When using Fe(NO 3)3as precursor,with the increase of OH −/Fe mole ratio,the surface area and total pore volume of catalysts increased and the average pore width of catalysts changed a little.On the contrary,when using FeSO 4as precursor,with the increase of OH −/Fe mole ratio,the surface area of catalysts reduced,while the total pore vol-ume of catalysts and the average pore width of catalysts increased.The results show that the pore structure of Fe(III)–SiO 2catalysts prepared by the second method are affected remarkably by the precursor species and the OH −/Fe mole ratio.The XRD patterns of S-Fe 3+,S-Fe 3+/2,S-Fe 2+and S-Fe 2+/2cata-lysts are illustrated in Fig.2.The pattern showed a typical broad peak,which indicated that silica gel used as a support was a pure amorphous structure.On the other hand,the XRD patterns did not show iron oxides peaks,even for catalyst with 6.2wt.%of iron (not shown in the figure).It may be proposed that the XRD techniques are not sensitive enough to detect little iron oxides because the higher background of XRD measurement caused by amorphous SiO 2.The oxidation state of Fe on the surface of catalysts was charac-terized by XPS and the results are presented in Fig.3.The binding energy of Fe 2p 3/2was determined to be 710.945eV,710.595eV and 710.975eV for S-Fe 3+,S-Fe 3+/1and S-Fe 3+/2catalyst,respectively,which was ascribable to Fe 2O 3[25].When FeSO 4was used as the precursor,the Fe 2p 3/2peak was found at 711.195eV,711.345eV and 711.850eV for S-Fe 2+,S-Fe 2+/1and S-Fe 2+/2catalyst,respectively,strongly suggesting that the iron on the catalysts was Fe(III)[21].When FeSO 4was used as precursor,the binding energy of Fe 2p 3/2Fig.2.XRD patterns of the Fe(III)–SiO 2catalysts.Fig.3.XPS spectra of the Fe 2p region for the Fe(III)–SiO 2catalysts.in catalysts were higher than that of catalysts prepared by Fe(NO 3)3.It was difficult to give an adequate explanation of increasing in the binding energy of Fe 2p 3/2yet.O 1s survey scan further indicated the oxygen status on the catalyst surface.As shown in Fig.4,the O 1s region can be fitted into four peaks,which are attributed to the chemisorbed oxygen,the lattice oxygen of SiO 2,the lattice oxygen of Fe 2O 3and the chemically or physically adsorbed water.Accord-ing to the reports [26,27],the chemisorbed oxygen can take an active part in the oxidation process and greatly improve the cat-alyst activity.It can be seen from Table 2that the percentage of chemisorbed oxygen of catalyst was improved when FeSO 4was used as precursor and the S-Fe 2+/1catalyst had the highest per-centage of chemisorbed oxygen.3.2.Characterization of the catalysts after the reactionThe catalyst was characterized by UV–vis-DRS and XPS to confirm the formation of Fe(II)–SiO 2when Fe(III)–SiO 2was irradi-ated by photon.The UV–vis diffuse reflectance absorption spectra of Fe(III)–SiO 2catalyst before and after reaction are shown in Fig.5.The results clearly shows a new broad absorption band at 505–525nm after irradiation which is characteristic band of [Fe(1,10-phenanthroline)]2+complex [17].It is accounted for that the Fe(III)–SiO 2on irradiation with photon isconverted into Fe(II)–SiO 2that would be complexed with 1,10-phenanthroline in solid state.The binding energy of Fe 2p for the catalyst before and after reaction is shown in Fig.6.It is observed that the binding energy of Fe 2p 3/2is slightly shifted to lower BE value from 711.345to 710.600eV after irradiation,which is due to the reduction of Fe(III)–SiO 2to Fe(II)–SiO 2during the irradiation.Fig.4.O 1s curve fitting of S-Fe 2+/1catalyst.T.Liu et al./Journal of Hazardous Materials 162(2009)860–865863Table 2XPS data of O element on the

photo-Fenton processesThe degradation of 100mg/L PAM in aqueous solutions under different conditions was preformed by using S-Fe 2+/1as a photo-Fenton catalyst at an initial solution pH of 6.8,and theresults are shown in Fig.7.In the presence of UV lamp,about 5%degradation of PAM in aqueous solution was observed,indicating that the degra-dation of PAM caused by direct photolysis is very limited.In the presence of 1.0g/L S-Fe 2+/1catalyst,the removal of PAM was less than 5%,which was caused by the adsorption of PAM on the catalyst.With 1.0g/L S-Fe 2+/1catalyst and 200mg/L H 2O 2in dark,the degra-dation of PAM was low,implying that the PAM degradation in the course of heterogeneous Fenton reaction is limited in neutral cir-cumstance.In the presence of UV and 200mg/L H 2O 2without anyFig.6.XPS spectra of the Fe 2p region for the S-Fe 2+/1catalyst:(a)Fe(III)–SiO 2and (b)Fe(II)–(1,10-phenanthroline)–SiO 2sample.catalyst,the concentration of PAM decreased significantly.It is due to the oxidation of PAM by •OH radicals formed direct photolysis of H 2O 2.In the presence of 1.0g/L S-Fe 2+/1catalyst,UV and 200mg/L H 2O 2,the concentration of PAM decreased rapidly and about 94%PAM degradation in 90min.As the leaching of Fe from Fe(III)–SiO 2catalyst was negligible (described as follows),the degradation of PAM in aqueous solutions was almost caused by the heterogeneous photo-Fenton reaction,indicating that S-Fe 2+/1catalyst exhibits a good photocatalytic activity in PAM degradation.It is assumed that Fe(III)species on the surface of catalysts transform to Fe(II)species under irradiation of UV light,then,the Fe(II)species generate •OH radicals by the decomposition of H 2O 2[28,29].At the same time,the UV light irradiates hydrogen peroxide to produce the •OH radicals.Finally,PAM is oxidized by •OH radicals.Therefore,the mechanism for the photo-Fenton degradation of PAM using Fe(III)–SiO 2catalyst as a heterogeneous catalyst is proposed below:H 2O 2+h →2•OH(1)Fe(III)−X +H 2O +h →Fe(II)−X +•OH +H +(2)Fe(II)−X +H 2O 2→Fe(III)−X +OH −+•OH (3)PAM +•OH →Intermediates →CO 2+H 2O(4)where X represents the surface of Fe(III)–SiO 2catalyst.The mineralization process of PAM aqueous solutions under dif-ferent conditions was measured and the results are shown in Fig.8.Only with 8W UV,there was almost no mineralization of PAM.In the present of 1.0g/L S-Fe 2+/1catalyst and 200mg/L H 2O 2in dark,about 20%TOC of PAM was removed after 180min,indicating that the mineralization of PAM by heterogeneous Fenton reaction is limited in neutral circumstance.In the presence of 8W UV and 200mg/L H 2O 2,the mineralization of PAM is significant,about 40%Fig.7.Degradation of PAM under different conditions:(a)1g/L S-Fe 2+/1catalyst,(b)8W UV,(c)1g/L S-Fe 2+/1catalyst

conditions:(a)8W UV,(b)1g/L S-Fe 2+/1catalyst +200mg/L H 2O 2,(c)8W UV +200mg/L H 2O 2and (d)8W UV +200mg/L H 2O 2+1g/L S-Fe 2+/1catalyst.TOC of PAM was removed after 180min.With the present 1.0g/L S-Fe 2+/1catalyst,8W UV and 200mg/L H 2O 2,the mineralization of PAM was significantly accelerated.After 180min,about 70%TOC of PAM was removed,suggesting that the S-Fe 2+/1catalyst show a significant photocatalytic activity for the mineralization of PAM.3.4.Effects of the precursor species and the OH −/Fe mole ratio on the PAM degradationTo check the photocatalytic activity of catalysts prepared by different methods,degradation of PAM in aqueous solutions by Fe(III)–SiO 2catalysts was evaluated and the results are presented in Fig.9.It was observed that the catalysts prepared with two pre-cursor species and different OH −/Fe mole ratio showed different photocatalytic activity.At the same OH −/Fe mole ratio,catalysts prepared with FeSO 4shown a higher photocatalytic activity than Fe(NO 3)3.The most effective catalyst seems to be that prepared with FeSO 4and the OH −/Fe mole ratio at 1.By using S-Fe 2+/1cata-lyst,98.6%of degradation was obtained after 120min.In contrast,S-Fe 3+/1catalyst gave rise to the less photocatalytic activity,which produced an efficiency degradation of 89.7%.The different photo-catalytic activity was observed when two precursors are used.The results are not clear,and it will be the aim of further work (iron oxidation state effect).3.5.Fe leaching from Fe(III)–SiO 2catalystsIn addition to having a high photocatalytic activity,stability is another important factor for a catalyst prepared.Theconcentra-Fig.9.Degradation of PAM by using different Fe(III)–SiO 2catalysts.Fig.10.Fe concentration in solution by using different Fe(III)–SiO 2catalysts.tion of Fe ions in solution with different catalysts was examined by ICP and the results are shown in Fig.10.It can be seen that there is no significant difference in the patterns of the curves.The concentration of Fe ions increased as reaction time increased,and reached a peak value,then followed by a decrease.The same phe-nomenon has been reported by Feng et al.[30],but the reason is still not clear.At the same OH −/Fe mole ratio,the Fe leaching from the catalysts prepared by Fe(NO 3)3was usually lower than the catalysts prepared by FeSO 4.The maximum concentration of Fe among all the catalysts was 0.17mg/L,suggesting that the Fe leach-ing from the Fe(III)–SiO 2catalysts is negligible,and the degradation of PAM aqueous solutions are almost caused by the heterogeneous photo-Fenton reaction in neutral circumstance.After 120min of the reaction,the percentage of Fe leached from the S-Fe 2+/1catalyst is only about 0.62%,the results also suggest that the catalysts have a long-term stability.4.ConclusionsFe(III)–SiO 2catalysts have been synthesized by two methods with Fe(NO 3)3and FeSO 4as precursors,and were characterized by the BET,XRD and XPS method.The percentage of chemisorbed oxygen on the surface of catalysts prepared by FeSO 4is higher than that prepared by Fe(NO 3)3.The results confirm the formation of Fe(II)–SiO 2when Fe(III)–SiO 2was irradiated by photon.The photocatalytic activities of Fe(III)–SiO 2catalysts were eval-uated by the degradation of PAM from aqueous solution in the photo-Fenton reaction and all the catalysts exhibited a better photocatalytic activities.However,the precursor species and the OH −/Fe mole ratio have influence on the photocatalytic activi-ties of the catalysts.At the same OH −/Fe mole ratio,the catalysts could present the better photocatalytic activities when using FeSO 4as precursor.The best efficiency for the degradation of PAM in heterogeneous photo-Fenton reaction was 94%degrada-tion in 90min and 70%TOC removal in 180min at an initial pH of 6.8.Finally,it was observed that Fe leaching from Fe(III)–SiO 2cata-lysts was negligible,indicating that the catalysts have a long-term stability and the degradation of PAM from aqueous solution are almost caused by the heterogeneous photo-Fenton reaction.AcknowledgmentsThe authors gratefully acknowledge the financial supports from the National Basis
