Chemical speciation and recovery of gold(I, III) from wastewater and silver by liquid–liquid extraction with the ion-pair reagent amiloride mono hydrochloride and AAS determination

A novel and low cost liquid–liquid extraction procedure for the separation of gold(III) at trace level from aqueous medium of pH 5–9 has been developed. The method has been based upon the formation of a yellow colored ternary complex ion associate of tetrachloro gold(III) complex anion, AuCl 4 − wit...
