Abstract

The electrochemical behavior was studied for SeO2 in the absence and presence of Succinic acid (SuA) and ‎Dithizone (DT) separately in 0.1M KCl solution. The Gold electrode was prepared in our laboratory from ‎gold wire 18K. The Gold wire was polished in Al2O3 piece put in woolen cloth and good washed. Gold ‎electrode was used as working electrode for measuring the voltammograms of SeO2 in 0.1M KCl at 18°C. ‎Stability constant and Gibbs free energy of interaction for SeO2 + Succinic acid and SeO2 + Succinic acid +  ‎Dithizone (DT) was done and their values were discussed.‎
