Mediated electrochemical oxidation is a promising technique for the destruction of organic compounds. Destruction of tributyl
phosphate (TBP) in normal paraffin hydrocarbon (NPH) in nitric acid medium containing electro-generated Ag(II) was studied.
Initially, the effect of uranium, presence of DBP along with uranium in the organic phase and direct electrochemical oxidation
without catalyst (Ag) on the destruction of 30% TBP/NPH system was evaluated. For a comparison, the rate of destruction of
NPH alone was studied. Further, radioactive laboratory waste solution was tested for the destruction of organic waste under
similar experimental conditions. The electrolyte used in the system was 0.5 M AgNO3 in 8 M HNO3 at 333 K. The uniqueness in all these experiments is the use of a double end open porcelain diaphragm for the isolation of
electrodes. Though there would be a slight reduction in the efficiency, two major hurdles viz., reduction in the concentration
of nitric acid and reduction in the volume of catholyte resulting in an increase in cell voltage were avoided. The problem
of the migration of Ag+/Ag2+ and accumulating at the cathode site was overcome by using double end open diaphragm and thorough mixing. The results revealed
that the rate of destruction of organics is favoured in the presence of uranium in organic phase and with increase in temperature.
