摘要

在含溴酚蓝的磷酸缓冲溶液中,应用循环伏安法于经预处理的玻碳电极上形成聚合物薄膜.结果表明,在-1. 0V~+1. 8V(vs.Ag/AgCl)扫描电位之间形成的薄膜具有较高的电活性和稳定性.该电极对抗坏血酸电化学氧化有催化作用,既使抗坏血酸的氧化电位负移了 270mV,又增大了其氧化峰电流.催化峰电流与抗坏血酸浓度在 2. 5~250μg/mL范围内呈良好的线性关系.

Abstract

A film of poly ( bromophenol blue ) was formed on a glassy carbon electrode by using cyclic voltammetry. A stable film could be obtained with a potential range from -1.0V to +1.8V(vs.Ag/AgCl). The experimental results showed that the poly ( bromophenol blue ) modified glassy carbon electrode could catalyse the oxidation of ascorbic acid. It decreased the oxidation potential by about 270mV but increased the peak current. Meanwhile, this electrode showed a good linear current response for the ascorbic acid range from 2.5 to 250 (g/mL.)
