Studies on Voltammetric Behavior of L-Cysteine at Silver Microdisk Electrode

Abstract

Abstract: 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 5.0×10^-5～2.0× 10^-3 mol/Lis linear.The method has been used for determination of mixed samples with satisfactory results.

Key words: Silver microdisk electrode, L-cysteine, Cyclic voltammetry
