In this paper, the voltammetric behavior of L-cysteine at silver microdisk elelectrode in 0.2 mol/L HAc-NaAc buffer solution was investigated. The mechanism of electrode reaction was discussed. The possibility of the determination of L-cysteine by cathodic stripping voltammetry was examined experimentally. The dependence of reduction peak current of Ag(L-Cys) on the L-Cys concentration in the range of 5. 0x10-5~2.0x 10-3 mol/L is linear.The method has been used for determination of mixed samples with satisfactory results.
