Extraction of uranium by a supported liquid membrane containing mobile carrier.
A study has been made of carrier-mediated transport of uranium(VI) by a liquid membrane of 7-dodecenyl-8-quinolinol (Kelex 100). Uranium is transported across the membrane and concentrated in a stripping acid. The apparent rate constant of uranium transport increases slightly with increase in carrier concentration and in the pH of the feed solution. Uranium can be effectively recovered from spiked sea-water through the liquid membrane without any preliminary treatment.
