dc.description.abstractThe electrochemical behaviour of the complex between L-ascorbic acid (AA) and Pb (II) was studied by using Square-wave voltammetry (SWV) and Cyclic voltammetry (CV). L-ascorbic acid forms a 1:1 complex with Pb (II) in 0.1 M sodium perchlorate at pH 5.0. It was found that the reduction processes of Pb (II)-ascorbic acid complex was irreversible. The stability constant of the Pb (II) - ascorbate complexes were evaluated with the De Ford-Hume procedure at different ligand concentrations using square wave voltammetry (SWV). The logarithm values of stability constant of 1:1 Pb (II)-ascorbic acid complex was found to be 0.908. Key words: Pb (II)-ascorbic acid, De Ford-Hume, Square-wave voltammetry (SWV), cyclic voltammetry (CV), stability constanten_US
