METHOD FOR REDUCING THE NEGATIVE IMPACT OF IMPURITIES ON ELECTRODES USED FOR THE ELECTROSYNTHESIS OF SODIUM CHLORATE

摘要

The invention relates to a method for countering the negative effect of an impurity on an electrode used for the electrosynthesis of sodium chlorate by means of an electrolyte. According to this method, during electrolysis a substance is added to the electrolyte that reacts with the impurity and prevents it from deteriorating the performance of the electrode. By way of example, the impurity is calcium (Ca²⁺) and the substance is phosphate (PO₄^3-).
