ABSTRACT:
Chlorine dioxide is formed by an autocatalytic electrochemical process from highly acidic chlorate solution containing a residual concentration of chlorine dioxide. Cathodic current is applied to the solution by an electrode which does not otherwise catalyze the chemical formation of chlorine dioxide from the acidic chlorate solution. High purity chloride dioxide is obtained while half the acid is consumed and half the water is produced as compared with a conventional chemical chlorine dioxide generating process.
