METHOD OF PREPARING AMMONIUM CHLORIRIDEATE Russian patent published in 2000 - IPC

Abstract RU 2161131 C1

FIELD: chemistry of iridium, more particularly preparation of ammonium chlorirideate. SUBSTANCE: chlorirideatic acid solution is subjected to electrochemical purification. Purification is carried out at cathodic current density of 15-40 A/sq.dm. Solution contains organic substances such as tributyl phosphate and/or sulfoxides and/or kerosene and/or octanol. Solution acidity is 1-2 N HCl. Purification over, ammonium chlorirideate is precipitated with ammonium chloride from solution. EFFECT: high recovery of iridium in processing any solutions, preparation of high- ammonium chlorirideate. 2 cl, 1 tbl
