Rapid solvent extraction of gold(III) with high molecular weight amine from organic acid solution


A novel solvent extraction separation method has been developed for the determination of gold in real samples. It involves selective and quantitative extraction of gold by N-n-octylaniline, a high molecular weight amine (HMWA), in xylene from aqueous sodium malonate medium at pH 1.0. The effects of concentration of malonate, extractant, metal ion, and pH and of various diluents, stripping agents and other substances on the quantitative extraction of gold have been assessed. The applicability of the method to binary mixtures, synthetic mixtures, alloys and pharmaceutical samples is discussed.
