Abstract
To obtain the desired specific adsorbents for chlorpyrifos to enrichment, separation and analysis of trace pesticides residue, molecularly imprinted polymer microspheres were prepared by precipitation polymerization using chlorpyrifos and methacylic acid (MAA) as template and functional monomer respectively. Computer simulation was employed to demonstrate the mechanism of the interaction between chlorpyrifos and MAA. The adsorption properties of chlorpyrifos, in acetonitrile for imprinted microspheres were evaluated by equilibrium rebinding experiments. Scatchard plot analysis revealed that there was a class of binding sites populated in the molecularly imprinted polymers (MIPs). The specificity of the imprinted microspheres was investigated by binding analysis using chlorpyrifos and related organophosphate pesticides. The results indicated that the obtained imprinted microspheres showed a good selectivity for chlorpyrifos.
