Method of purifying neutral organophosphorus extractants |
| abstract |
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 + state followed by contact with a macroporous anion exchange resin in the OH - state, whereupon the resins take up the acidic contaminants from the extractant, purifying the extractant and improving its extraction capability. |
