The redox behavior data for thallous chloride in the absence and presence of pectin (1% w/w) using 0.1 M KF solution has been electro-chemically investigated using a cyclic voltammetry technique .were evaluated cyclic voltammetrically. This work emphasizes the current and potential sites at which monovalent thallous is reduced and oxidized in KF solutions that are vital to the electrochemical evaluation of thallium. The measurements were done for possible reduction and oxidation reactions by cyclic voltammetry experiment using a glassy carbon, silver-silver chloride, a platinum wire as working, reference, and a counter electrode. The effect of TlCl concentration for alone cyclic voltammetry and effect of pectin (1% w/w in H₂o) concentration were studied and their values were discussed. The difference in kinetic, thermodynamic parameters for interaction of TlCl with pectin (1% w/w) were evaluated and their values prove electrodes interaction between the two .
