Abstract: The electrochemical behavior of nickel chloride in citric acid aqueous solution (0.1M) in the presence of potassium ferrioxalate K3Fe(Oxalate)3 (KFOx) as moderator sensor and by the use of gold working electrode (GWE) was studied. Since nickel ions do not show any peaks in acidic media, but after adding potassium ferrioxalate K3Fe(Oxalate)3 (KFOx) as a sensor, two redox peaks of nickel ions were obtained. (KFOx) sensor indicating the appearance of nickel ion peaks. Two redox couples of waves were obtained attributed to [Ni(II)-Ox-Fe(III)]/[Ni(III)-Ox-Fe(III)]and[Ni(II)-Ox-Fe(III)] /[Ni(II)-Ox-Fe(II)]. The cyclic voltammetry for NiCl2 and its interaction with diphenylthiocarbazone, dithizone was studies at three different temperatures, 293.15, 303.15 and 313.15K. Different thermodynamic and kinetic parameters of interaction of nickel ions with dithizone were evaluated from the cyclic voltammograms. The estimated cyclic voltammetry values were discussed. Molecular docking was carried out to predict the binding between diphenylthiocabazone, dithizone ligand with the receptor of human liver cancer (3cmf). We can propose that interaction between the 3cmf receptors and the ligand is possible.
