以糠醛和邻苯二胺合成的双席夫碱糠醛缩-邻苯二胺（以下简称FFDB）为中性载体,将其与碳粉混合,以液体石蜡为粘合剂,制备了一种新型的铜离子选择性电极。电极对Cu2＋的能斯特响应浓度范围为5.00×10-6～1.00×10-2mol/L,检测下限为1.65×10-6mol/L,电极的响应时间小于30 s,稳定性好,使用寿命长。可成功的用于工业废水中的Cu2＋进行测定。

A sensitive film of carbon paste doped with furfural -1,2 -diaminobenzene as a carrier was prepared for construction of Cu （ Ⅱ） - selective electrode. The Nernstian response concentration of electrode to Cu （Ⅱ） was over a range of 5. 00× 10^-6 - 1.00×10^-2 mol/L, with a detection limit of 1.65×10^-6 Ⅱ mol/L. The response time of the elec- trode was less than 30 s with good stabiligy and long life and it was used to determine the copper contents in the wastewater, and the result was excellent.
