Abstract

Настоящее изобретение относится к электроду для электрохимической выработки гипохлорита. Электрод включает подложку из вентильного металла с покрытием из каталитической системы, состоящей из двух наложенных один на другой слоев, имеющих различный состав и реализующих различную активность относительно анодной выработки гипохлорита из растворов хлорида. Такой электрод имеет большой срок службы в катодных условиях работы, придающих ему способность к самоочищению при использовании в комбинации с таким же электродом с периодическим изменением полярности. Более того, дезактивация электрода в конце срока его службы происходит за две последовательные стадии, позволяя планировать его замену достаточно заблаговременно.
