The extraction of zinc from ammoniacal/ammonium sulphate aqueous media using LIX 54 has been studied. The metal extraction rate has been examined and also the e †ect of temperature on the extraction of zinc (\*HΒ‘ \ [8Γ‰8 kJ mol~1). The e †ect of the aqueous pH, and therefore zinc ammine complex forma

The extraction-stripping reaction of Cu(II) by LIX 54 in IberΒ―uid from aqueous ammonium sulfate medium at pH 8.5 has been investigated. The effects of pH, metal ion, extractant concentration as well as the loading capacity of the reagent were studied. The extraction equilibrium constant for copper w
