A novel method has been developed for the extraction chromatographic separation of gold(III) with N-n hexylaniline (N-n-HA) liquid anion exchanger coated on silanised silica gel. Its quantitative extraction has been achieved by 1.5 mol L-1 hydrochloric acid and eluted with ammonia buffer solution. The various parameter studied viz. Effect of acid concentration, stripping agent for ext raction and elution have been evaluated, flow rate and effect of varying concentration of gold(III). Method extends its application from analysis of ayurvedic samples containing gold and analysis copper-silver-gold alloy permits quantitative recovery of gold.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
