Abstract:
1. A process for producing an electrolyte, comprising: producing in a mixing device a metal ion containing mixed solution from a waste product that contains metal ions; providing an anion exchanger to directly receive from the mixing device the ion mixed solution; passing the ion mixed solution through the anion exchanger and then to an electrochemical system sized and configured to produce a prepared metal ion mixed solution; and bringing electrodes into contact with the prepared metal ion mixed solution such that at least impurity metal ions are selectively removed from the prepared metal ion mixed solution; wherein the impurity metal ions are selectively removed by a selectively permeable ceramic membrane comprising pores that separates the prepared metal ion mixed solution and a cleaning solution from one another, the ceramic membrane comprises an organic complexing agent that forms metal complexes in the pores of the membrane.
