Abstract

The invention relates to a system for the electrolytic production of sodium chlorate starting from a sodium chloride brine buffered with phosphate and having a reduced or zero chromium content. The system comprises electrolytic cells of the undivided type with intercalated cathodes and anodes; in one preferred embodiment, the cathodes consist of steel perforated sheets activated with a Fe-Mo alloy coating.
