Extraction of Gold(III), Palladium(II), and Platinum(IV) by l-[2-(2,4-dichlorophenyl)-4-propyl-l,3-dioxolan-2-ylmethyl]-1H-l,2,4-triazole from Hydrochloric Acid Solutions

摘要

The extraction of gold(III), palladium(II), and platimum(IV) with l-[[2-(2,4-dichlorophenyl)-4-propyl-l,3-dioxolan-2-yl]methyl]-1H-l,2,4-triazole from hydrochloric acid solutions into toluene has been studied. The extraction follows the anion-exchange mechanism. The concentration constants and thermody-namic parameters of the extraction reaction have been calculated. The reagent is proposed for use in the extraction of the sum of precious metals.
