Method of purifying neutral organophosphorus extractants

摘要

A method for removing acidic contaminants from neutral mono and bifunctional organophosphorous extractants by contacting the extractant with a macroporous cation exchange resin in the H.sup.+ state followed by contact with a macroporous anion exchange resin in the OH.sup. - state, whereupon the resins take up the acidic contaminants from the extractant, purifying the extractant and improving its extraction capability.
