ZIRCONIUM SEPARATION USING SOLVENT EXTRACTION

摘要

first extracting zirconium solution containing hafnium with Versatic acid 10 of 0.5-2.0M in organic solvent, second extracting the organic component with aqueous solution containing HCl of 0.5-2.0M; obtaining ZrOCl28H2O crystal by vaporizing and concentrating an aqueous solution containing Zr; and hydrolyzing ZrOCl28H2O crystal with amnia, and baking.
