摘要：

Several Potential extractants were considered as the active compound in supported liquid membranes (SLMs) for the selective extraction of dicyanoaurate(I) from alkaline process solutions. SLM systems containing primary, secondary, tertiary, and quaternary amines, in which the extraction and back-extraction is achieved in one step, are proposed. The various SLMs were compared using flow-injection analysis (FIA). They were evaluated on the basis of their stability, selectivity, and respective permeability for gold.
