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.
