Экстракционное отделение, концентрирование и спектрофотометрическое определение золота реагентом МВТИ

Abstract

A new, simple, sensitive, efficient spectrophotometric procedure for the determination of gold was developed. The method is based on the reaction of [AuCl4]- with 2-[2-(4-metoxyphenylamino-)- vinyl]-1,3,3-trimethyl-3H-indolium reagent to form colored ion associate extractable by various organic solvents. The established method was applied to the determination of gold in model samples and enriched polymetallic ores.
