Notes:
Cation exchange membranes were prepared with 2,3-epithiopropyl methacrylate (ETMA)-2-acrylamide-2-methylpropane sulfonic acid (AMPS) copolymers. Transport of uranyl ion against its concentration gradient through the membranes was investigated by using a system containing carbonate solution (left side) and uranyl ion (and other metal ion) solution (right side). ETMA-AMPS copolymer membranes transported UO2+2 against its concentration gradient. Na2CO3 solution was most effective as receiving solution for the uphill transport of UO2+2. The transport was greatly affected by the composition of the copolymer membranes. Highly selective transport of UO2+2 from the solution containing UO2+2 and other metal ions was observed by using Na2CO3 solution in the left side. The main driving force for this transport of UO2+2 is the high complex-formation ability of UO2+2 with CO2-3.
