摘要：

The extraction-stripping reactions of copper with LIX 973N in Iberfluid have been studied. The effect of equilibration time, temperature, ammonium carbonate concentration, aqueous pH, extractant and strip solution concentrations as well as the loading capacity of the reagent were investigated. The loaded organic was found to pick up some ammonia, which has been selectively stripped at controlled pH. The number of stages required for the extraction and stripping of copper was also evaluated. The results are used to assess the conditions for purification of ammoniacal industrial waste solutions containing copper. (C) 1999 Elsevier Science B.V. All rights reserved.
