摘要

Abstract

A general protocol was described for fabricating uniform molecularly imprinted polymer (MIP) particles

via

controlled living radical precipitation polymerization at ambient temperature. By adopting glutathione as model template

benzyl dithiocarbamate as iniferter agent

4-vinylpyridine as monomer

and ethylene glycol dimethacrylate as cross-linker

it is demonstrated that the polymerization parameters including the iniferter concentration

monomer loading and molar ratio of cross-linker to functional monomer have profound effect on the final particle size and recognition property of the MIP particles. The batch static binding experiments were carried out to estimate the adsorption kinetics

adsorption isotherms and selective recognition of the MIP particles. The adsorption behavior followed the pseudo-second order kinetic model

revealing that the process was chemically carried out. Two adsorption isotherm models were applied to analyze equilibrium data

obtaining the best description by Langmuir isotherm model. In addition

the MIP particles also could selectively recognize glutathione over similar analogs

indicating the possibility for the separation and enrichment of the template from complicated matrices.
