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!
