| Abstract: | A simple and sensitive electrochemical method was described by using differential pulse voltammetry for the determination of captopril(CPT).The method was based on the adsorption and oxidation of CPT at a gold electrode.The electrochemical behavior of CPT on the electrode was investigated with cyclic voltammetry and differential pulse voltammetry.Under the optimized experimental conditions,the voltammetric response was proportional to the concentration of CPT over the range from 0.217 to 3.04 mg/L with a co... |
