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.)
