In modern agriculture,extensive use of pesticides to preserve crops from pests has raised serious environmental and food safety problems because of the harm for our healthiness.As one of important branches of the instrumental analysis in modern days,electrochemical analysis technology shows great potential and advantages in analysis fields and more applications in pesticide residues.In this work,a hybrid nanocomposite consisting of copper nanowires(Cu NWs)and Graphene(GR)/CTS was prepared as an excellent catalyst for methyl parathion electrooxidation.Through a simple way to obtain a mixed Cu NWs/GNs-Chit hybrid nanocomposites,the combination of them formed structure similar to a overhead network,to provide a beneficial platform for the detection.Under the optimized operational conditions,the developed electrochemical sensor showed a specific and excellent performance with a good sensitivity,selectivity and wide dynamic range toward the quantification of methyl parathion.The results implicate the applicability of CuNWs/GNs-Chit hybrid nanocomposites for fast,simple,sensitive and elective analysis of OPs,which may open a new avenue in monitoring Ops.
