Kotesu Posted June 17, 2013 Share Posted June 17, 2013 I'm looking into a process handling an aqueous feed solution containing metal salts as well as up to 30% of a polar organic solvent like acetone or methanol. The goal is to separate out the metal cations by element. So far, I've been able to identify a few promising approaches to the point that I can start building a simple working demo. The problem is, I'm attempting to procure an anion-exchange membrane that can tolerate the organic solvents and I'm at a loss with my current suppliers. Does anybody know of a membrane or membrane supplier that can survive in that environment? Many thanks! Link to comment Share on other sites More sharing options...
THX-1138 Posted July 4, 2013 Share Posted July 4, 2013 Are the solvents throwaway? Rather than separating out the metal ions in the presence of the solvents, can you work the other way round and remove the solvents and then process the metals?
