摘要: 在邻苯二酚-甲醛-NaOH介质中,于-0.1~+1.5(vs,SEE)扫描范围内用循环伏安法制作修饰玻璃碳电极。电极可用于水中痕量铜的测定,其灵敏度比未修饰的玻璃碳电极提高35倍以上,定量下限为0.1ng/ml。

关键词: 修饰电极, 邻苯二酚, 铜, 阳极溶出伏安法

Abstract: This paper reported the glassy carbon electrode modified by cyclic voltammetrybetween-0. 1and + 1. 5 V(vs. SCE)in an aqueous solution containing catechol,formaldehyde andtalium hydroxide. The modified electrode can be applied to the determination of copper(Ⅱ) in water,and its sensitivity is about 35 times higher than that of unmedified glassy carbon electrede, Thequantitative limit with this modified electrede is 0. 1 ng/ml.

Key words: Modified electrede, catechol, copper, Anodic stripping voltammetry.
