Abstract
A novel chemically modified electrode containing Rh(III)terpyridine complex was
achieved on the surface of glass carbon electrode by sol-gel technique. The electrochemical
behavior of modified electrode was characterized by cyclic voltammetry in detail. The film
electrode obtained was very stable and exhibited electrocatalytic response for oxidation of
ascorbic acid. Results showed at bare GC electrode, a small oxidation peak current was
observed at about 0.42 V and a well-formed sharp catalytic oxidation peak at about -0.08 V
was observed at Rh(III)terpyridine complex modified electrode. The transfer coefficient (?)
for electrocatalytic oxidation of ascorbic acid and the diffusion coefficient of this substance
under the experimental conditions were also investigated
