ABSTRACT:
An improved process for recovering oxyacids of chlorine or salts of such acids by the electrolysis of sea water or of salt solutions contaminated by metal ions is disclosed wherein extensive build-up of contaminating calcium ions and/or magnesium ions as the corresponding hydroxide on the cathode is prevented by the addition of precipitating chemicals at a pH value above 9. In accordance with the invention, the precipitating chemicals are not added to the sea water or salt solution contaminated by metal ions until a layer has been built up on the cathode such that the current efficiency has increased to a value in excess of 90 percent.
