Abstract: Simazine (CAT) is one of the triazine herbicides, and reported to be an endocrine disrupting chemical. Recently, we have reported the molecularly imprinted polymer selective to CAT (CAT-MIP). CAT-MIP was composed of the methacrylic acid (MAA) as the functional monomer and the ethylene glycol dimethacrylate (EDMA) as the cross-linker, and bound more CAT selectively than the structural analogues. The reductive current of CAT was detected by amalgamated gold electrode which was alloyed with mercury. CAT sensing based on CAT-MIP was performed by extracting CAT through the CAT-MIP particles packed column, and then the reductive current of the eluted solution was measured electrochemically. The reductive current of CAT depended on the concentration of CAT loaded. CAT sensor showed higher response to CAT than the structural analogues. The environmental standard limit for water quality, CAT 3ppb, was detected more than the structural analogues. Thus, CAT sensor was shown to be selective to CAT. (author abst.)
