以苯甲醛缩硫代氨基脲铜(Ⅱ)配合物为载体的高选择性硫氰酸根离子电极的研究

Study on Highly Selective Thiocyanate Electrode Based on Benzaldehyde Thiosemicarbazone Copper(Ⅱ) Complex as Neutral Carriers

本文研究了以苯甲醛缩硫代氨基脲铜(Ⅱ)[Cu(Ⅱ)-BATA]为中性载体的PVC膜电极。发现该电极对SCN-具有优良的电位响应特性,并呈现反Hofmeister选择性行为。采用紫外可见光谱法研究了阴离子与载体的作用机理,并将该电极初步应用于实际废水样品分析,结果满意。

A new highly selective thiocyanate electrode based on benzaldehyde thiosemicarbazone copper （Ⅱ） complex[Cu （Ⅱ）-BATA] as neutral carrier was developed, which displayed an anti-Hofmeister selectivity sequence. The response mechanism was discussed in view of the UV spectroscopy technique. The electrode can be applied to analysis of waste water, and the result obtained is fair agreement with the result given by HPLC methods.
