Uniformly imprinted polymer microspheres were prepared by precipitation polymerization in ***(monocrotophos),MAA(methacrylic acid),EGDMA(ethylene glycol dimethacrylate) and AIBN(azobisisobutyronitrile) were used as template,functional monomer,crosslinker and initiator,*** and IR spectra were used to demonstrate the mechanism of the interaction between MCP and *** was found that one MCP was entrapped by three MAA molecules in *** model was used to fit the adsorption data,the results showed that the MCP imprinted polymer microspheres showed specific binding sites to the *** data obtained in equilibrium adsorption experiments were processed by Scatchard analysis,the dissociation contents(KD1) and the apparent maximum binding capacity (Bmax1) were KD1=0.062?mmol/L,Bmax1=3.26?μmol/g for high affinity binding sites and KD2=3.03?mmol/L,Bmax2=65.70?μmol/g for low affinity binding sites,*** MCP imprinted polymers have showed higher affinity to MCP than to the other organophosphorus pesticide *** the imprinted polymers microspheres can be used for trace pesticide residue separation,enrichment and analysis.
