METHOD FOR PRODUCTION OF FINE-DISPERSED ARSENIC BY ELECTROLYSIS OF WATER-ALKALI SOLUTIONS OF COMPOUNDS THEREOF Russian patent published in 1994 - IPC

Abstract RU 2009276 C1

FIELD: arsenic production. SUBSTANCE: arsenic of purity 99% and higher is extracted by electrolysis of water-alkali solutions of compounds thereof on a cathode made of a barrier-effect metal such as titan. The cathode may have either an untreated surface or a surface coated with titan nitride or titan oxide. EFFECT: simplified electrolyzer design; enabled industrial-scale production. 1 tbl
