Influence of surface area of counter electrodes in electro-denitration process
Using anodes of different surface area with the same cathode, electrolytic reduction of 4 M HNO3 was carried out in constant current mode to quantify the energy loss due to temperature rise. Rate constants and enegy efficiencies were compared under applied current densities using anodes of different...

| description | Using anodes of different surface area with the same cathode, electrolytic reduction of 4 M HNO3 was carried out in constant current mode to quantify the energy loss due to temperature rise. Rate constants and enegy efficiencies were compared under applied current densities using anodes of different surface area. Based on the results, anodes with low surface area compared to the working electrode is not a suitable option during electrolytic denitration. Testing of a platinum electroplated titanium electrode as an anode for its life assessment suggested electroplating is not a viable option under harsh conditions, encountered in spent nuclear fuel reprocessing.
