Abstract
The redox mechanism of Ce(IV)-amine in the nitric acid medium was investigated by the spectrophotometric method. The Cc(III) formation by the redox reaction of Ce(IV)-amine produced the absorption peak at around 295 nm. From the data obtained at this absorption peak, it was concluded that the Ce(IV)-amine redox reaction followed the first order kinetics. The increase of a stability constant in Ce(IV)-amine complex increased the reduction action of the amine, resulting in the increase of Ce(IV)-amine redox reaction rate. From the Arrhenius plot, 11.09 kcal/mol of activation energy in dissociation of Ce(IV)-ethylenediamine complex was obtained.
