摘要
The use of different amines, Hostarex A327 (tertiary), Amberlite LA2 (secondary) and Primene JMT (primary), as carriers in the facilitated supported liquid membrane transport of metal-cyanide complexes, with special attention to gold, along with the addition of neutral organophosphorous derivatives (Lewis bases) to the amine organic phase as synergistic agents for the transport of Au(CN)(2)(-), at alkaline pH values and selectively against other metal-cyano complexes, is investigated.
