以双酚A (Bisphenol A, BPA)为模板, 氨基化硅胶为载体合成了对BPA有特异选择性的表面分子印迹聚合物(surface molecularly imprinted polymer, sMIP). 然后以聚氯乙烯(PVC)为支撑基质, 通过相转化过程(phase inversion process)制成BPA分子印迹聚合物膜, 将聚合物膜固载到处理过的金电极表面, 制成电流型双酚A电化学传感器. 优化了pH值、温度等实验条件, 结果表明在10～120 μg/mL范围内对双酚A有良好的线性响应(R＝0.9971). 传感器用于实际水样的测定, 结果令人满意.

Surface molecularly imprinted polymer (sMIP), which has specific selectivity to bisphenol A (BPA), was synthesized using BPA as template molecules and aminated silica gel as carrier. Based on that, MIP membrane was prepared by a phase inversion process using polyvinyl chloride (PVC) as support substratum and the amperometric sensor was constructed through immobilization of the MIP membrane on golden electrode surface. The sensor displayed a good linear range of 10～120 μg/mL under optimized pH and temperature conditions. The water samples were determined with satisfactory results.

Key words: bisphenol A, surface molecularly imprinted polymer, phase inversion process, electrochemical sensor
