摘要
双酚S是一种新型的环境污染物,它作为双酚A的替代物,主要用于生产聚碳酸酯、环氧树脂等高分子材料。研究表明双酚S不仅具有与双酚A类似的内分泌干扰效应,而且具有较强的致畸、致癌作用,因此实现双酚S的检测具有重要的意义1。目前,双酚S检测方法主要为色谱法,然而此类方法存在仪器成本高、装置体积大、操作程序复杂等缺点。聚合物敏感膜离子选择性电极是化学传感器的一个重要分支,由于其具有操作简便、价格低廉且易于实现现场监测等优点,在环境监测领域得到广泛应用2。固体接触式电极更加持久耐用,不需要特别维护保养,易于小型化。鉴于此,我们发展了全固态双酚S分子印迹聚合物离子选择性电极3-4,利用可重复使用的纳米多孔金做为传导层,成功实现了双酚S的高灵敏电位检测,检出限可达0.09μM。
An all-solid-state polymeric membrane ion-selective electrode for determination of bisphnol S is described.It is based on a molecularly imprinted polymer as a receptor for molecular recognition,which can be synthesized by precipitation polymerization using bisphenol S as the template molecule.A nanoporous gold film which is in situ formed on the gold electrode surface by electrochemical alloying/dealloying method is used as solid contact.Under optimized conditions,the proposed membrane electrode is proportional to the concentration of BPS in the range of 0.2 to 2μM.The detection limit was calculated to be 0.09 μM(3σ).The MIP-based sensor shows excellent selectivity,rapid response time and satisfactory long-termstability.The potentiometric sensor has been successfully applied to the determination of bisphenol S in drinking bottles.
