ABSTRACT:
A process for diminishing the concentration of a metal complex from a solution containing said complex by the addition of an optionally fused and/or optionally substituted heterocyclic compound. The added compound is a solubility-enhancing compound that enhances the solubility of said complex in a second solution. Thereafter the solution containing said complex can be extracted with the second solution.
