Kinetic parameters of Zn (II) in presence of ligand l-lysine, l-aspartic acid, l-glutamic acid, larginine, l-tryptophan and l-tyrosine at pH 7.50 ± 0.02 and at constant ionic strength μ = 0.1 NaClO4 have been evaluated. The reductions in all these cases were found to be quasi reversible and diffusion controlled. The values of kinetic parameters for the electrode processes viz ,  and ks have been evaluated using Gelling’s treatment1 and Er 1/2 values were also calculated for quasi reversible electrode processes.
