W. Mickler et E. Uhlemann, LIQUID-LIQUID-EXTRACTION OF COPPER FROM AMMONIACAL SOLUTION WITH CYCLOHEXYL-SUBSTITUTED BETA-DIKETONES, Separation science and technology, 28(17-18), 1993, pp. 2643-2650
The extraction of copper from ammoniacal solution was studied with dif
ferent cyclohexyl-substituted beta-diketones. For comparison with LIX
54, the extraction parameters were determined for their dependence on
the chain length of the substituent as well as on the influence of pH
and the concentrations of copper and ammonia.
