EXTRACTION SYSTEM FOR ZIRCONIUM IONS SEPARATION FROM AQUEOUS SOLUTIONS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention refers to extraction methods for metal ion extraction and concentration from aqueous solutions and can be used for zirconium separation from compound ion solutions with hydrogen chlorine acid. Invention rests on zirconium ion ability to be extracted in layer system water - ammonium sulphate - potassium bis-(alkylpolyoxyethylene) phosphate (oxyphos-B), [CnH2n+1+1O(C2H4O)m]POOK, where n=8-10, m=6 in ratio as follows, wt %: ammonium chloride - 10-15; oxyphos-B - 10-15; water - to 100. ^ EFFECT: possibility for quantitative zirconium ion separation from aqueous solutions thus avoiding application of expensive, fire-hazardous and toxic substances. ^ 2 tbl, 1 dwg, 9 ex
