Abstract: Using methylacrylic acid as a polymer matrix, trichlorfon as a template molecule,we prepared trichlorfon molecularly imprinted polymers(Tri-MIPs) that match up with template molecules in space structure and the binding sites by molecularly imprinting technique.The surface features of the polymers were analyzed by scanning electron microscopy.The synthesis of the Tri-MIPs,including the binding character,as well as the absorption and recognition ability was investigated.The column was packed with molecularly imprinted polymer.The chemiluminescence system was established for the determination of trichlorfon based on KMnO4 and HCl.The linear range of proposed method is 1.0 ×10-7 ~7.0 ×10-5 g/mL,the regression equation is I=425c(×10-7 g/mL)+356 and the correlation coefficient is 0.9913.The relative standard deviation is 3.1%.The detection limit,calculated following the 3s IUPAC criteria,is 2.8 ×10-8 g/mL.
