| 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. | ||||
