The nano cadmium chloride (NCCl) was prepared by ball milling of normal CdCl2. The redox behavior for nano cadmium chloride (NCCl) was explained by Cyclic Voltammetry in the presence and absence of ligand Glycine using glassy carbon electrodes in 0.1M HCl supporting electrode. Scan rates were done for explaining the redox behaviors for cadmium chloride in absence and in the presence of amino acid, glycine. Stability constants for the interaction of cadmium chloride with glycine were evaluated.The stability constants and Gibss free energies of interaction evaluated for interaction between nano cadmium chloride (NCCl) and glycine in 0.1M HCl are decreased by increasing nano cadmium chloride concentrations favoring more complex interactions. All mechanisms were discussed.
