Jun 01, 2000· The equilibrium constants of copper and iron were determined for the copper (II)-iron (III) -LIX984-Orfom SX-1 system. The average equilibrium constants of copper (II) and iron (III) were estimated to be 15.0±4.2 and 0.00030±0.00013 respectively. The results of extraction experiments show that LIX984 is a very selective copper (II) extractant.
