Abstract

It is shown experimentally that deterioration of supported liquid membrane of LIX64N for copper extraction is caused by at least two reasons. One, as has been pointed out by many authors, is wash-out of extractant (LIX64N) and the other noted for the first time, is contamination by some unknown substances dissolved from rubber and/or soft polyvinyl chloride into feed, stripping and membrane liquids.
