Abstract
|
|
|
|
The electrochemical reduction of uranyl ion at the dropping mercury electrode and/or mercury microelectrode has been studied in propanediol-1,2-carbonate (PDC) by voltammetric techniques. The position of peak potentials, the nature of limiting currents, their dependency on temperature and on concentrations, reversibility of electrode reactions, and influence of addition of phenol are described. The influence of PDC in aqueous solution of uranyl ion was also described. The values of kinetic parameters, viz., transfer coefficient, formal constant for the electrode reactions bave been determined by Koutecky's method as extended by Meites and Israel. The values of ΔH, ΔG and ΔS have also been calculated.
