Abstract：A new molecular imprinted electrochemical sensor has been developed for
detection of 3,5-Xylyl methylcarbamate(XMC) by combination of Graphene doped
Gold nanoparticle. The molecularly imprinted polymers (MIPs) was synthesized on
Graphene doped Gold Nanoparticle modified glassy carbon electrode surface by
using XMC as template molecular, methyl acrylic acid as functional monomer, and
ethylene glycol maleic rosinate acrylate as cross-linker. The electrochemical
performance of the imprinted film was studied with respect to its response to
hexacyanoferrate(Ⅲ) as a probe and characterized by cyclic voltammetry (CV) and
differential pulse voltammetry (DPV). Under the optimum conditions, the results
show that the peak current sensor and CBF concentration have a good linear
relationship over the range from 1.0×10-7 to 2.0×10-5 mol / L .The detection limit was
2.8×10-8
Key words：3,5-Xylyl methylcarbamate; gold doped graphene nanoparticle; molecularly imprinted electrochemical sensor; ethylene glycol maleic rosinate acrylate mol/L（S/N=3）. Meanwhile, the sensor exhibited high adsorption capacity
and good selectivity for target XMC. The results for the recovery of standard
addition of XMC in water were satisfactory with the sensor.
