Different Approaches For Metal Ion Separations:

In the previous section, we have seen the effect of some of the variables on extraction. It is not practically feasible to use all of them for affecting separations. However, it is up to you to use some of them intelligently to optimize the conditions for the separation of a given set of metal ions. The conditions are to be so chosen that the separation factor is as large as possible. It is possible to separate individual metal ions from multimetal ion mixtures by involving several steps. In devising the separation procedures, besides the decontamination factor or purity, emphasis is generally laid on yield or recovery. Another point that has to be kept in mind is that the recovered metal ion should be in such a form that it can be processed further easily. At this point, it becomes important to realize the importance of stripping in liquid- liquid extraction.
