摘要
A carbon-paste electrode was modified with copper-cobalt hexacyanoferrate by consecutive potential cycling. The kinetic parameters were calculated for the electroactive species. The resulting electrode exhibited electrocatalytic activity towards the oxidation of captopril. The kinetics of the electrocatalytic reaction was studied. A linear relationship was observed between anodic current and the concentration of captopril in the range of 5.0 x 10(-6)-3.1 x 10(-5) mu M with a detection limit of 4.2 mu M (S/N = 3). The modified electrode was used in the analysis of captopril tablets successfully.
