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 -1.0 V to +1.8 V(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).
