Application of Molecular Imprinting Technique in Organophosphorus Pesticides Detection
Molecular imprinting technique offers a means of producing practical materials that are able to recognize a certain molecule in terms of shape, size and chemical functionality. In order to obtain a highly selective recognition of organophosphorus pesticides (OPPs), we synthesized molecularly imprinted polymers (MIPs) using pirimiphos-methyl as the template, methacrylic acid as the monomer and ethylene glycol dimethacrylate as the crosslinker. After po-lymerization, molecularly imprinted solidphase extraction (MISPE) was used for the selective preconcentration of OPPs. The preparation methods and syn-thesis conditions of MIPs were discussed, and the specificity of MIPs and nonimprinted polymers were investigated. The results showed that MIPs enable the selective extraction of pirimiphos-methyl successfully from water sample, and demonstrated the potential of MISPE for selective and cost-effective sample pretreatment.
