Abstract: A molecularly imprinted polymer(MIP) for toluene was synthesized by precipitation polymerization using toluene as porogenic template,methacrylic acid as functional monomer and divinylbenzene as crosslinker.The recognition abilities of the obtained MIP and control polymer were investigated by the classical steady-state binding method.Experiments showed that the imprinted polymer exhibited a much higher capacity than that of the control polymer for binding to toluene.The maximum amount bound by the MIP was 21.6 mg/g.The proposed MIP was successfully applied to the enrichment of toluene in tap water samples with recoveries ranging from 92 % to 103 %.
