METHOD OF PURIFYING PHOSPHORIC ACID AFTER SOLVENT EXTRACTION

摘要

METHOD OF PURIFYING PHOSPHORIC ACID AFTER SOLVENT EXTRACTION A method of purifying phosphoric acid after solvent extraction to remove residual amounts of an immiscible organic carrier including contacting the phosphoric acid with a sorbent which sorbs or takes up the residual amount of organic carrier and separating the phosphoric acid from the organic carrier-laden sorbent. The method is especially suitable for removing residual organic carrier from phosphoric acid after solvent extraction uranium recovery.
