Compact Anode of Multi-Layer PbO2 on Titanium used for Electro synthesis of Sodium Perchlorate
Abstract
Experimental results are presented for the preparation of an electrode to replace platinum in the perchlorate cell. Compact anode of multi-layer lead dioxide on titanium (TSLD) anode has been developed for obtaining a suitable anode size of geometrical electrode shape and type of joining and assembling within the electrochemical cell. This can be considered as a feeding behavior by D.C. current and the suitable quantity of anode electrode to apply cell electrolysis of perchlorate production of high current application.Current-potential curves of the electrolytic oxidation of chlorate were determined. The polarogram obtained has two potential stages; the lower one is the potential of oxygen evaluation and the higher one is the potential of perchlorate formation which is less than that reported for the platinum anode by 0.3 V.The prepared TSLD anode has been used successfully in the presence of certain additive (NaF), as a replacement for platinum anode in sodium perchlorate preparation experiments.
