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 UO 2+ 2 against its concentration gradient. Na 2 CO 3 solution was most effective as receiving solution for the uphill transport of UO 2+ 2 . The transport was greatly affected by the composition of the copolymer membranes. Highly selective transport of UO 2+ 2 from the solution containing UO 2+ 2 and other metal ions was observed by using Na 2 CO 3 solution in the left side. The main driving force for this transport of UO 2+ 2 is the high complex‐formation ability of UO 2+ 2 with CO 2− 3 .
