title: Study of the transport of silver across a supported liquid membrane containing sulphide podand.
abstract: The transport of silver through a supported liquid membrane saturated with a polydentate neutral ionophore 1,12-di-thienyl-2,5,8,11-tetrathiadodecane in m-chlorotoluene has been studied. Thiosulphate was used as the stripping solution. The influence of the feed solution composition, the type of a microporous polypropylene Celgard support, the ratio of feed/receiving solution volume, and the initial Ag concentration on the rate of transport of silver was examined. Transport of Ag is selective towards Cu(II), Pb and Zn, but these cations affected the rate of the Ag flux.
