FIELD: analytical methods.
SUBSTANCE: invention is directed to provide a method for determining gold(III) in secondary raw materials and scraps, in natural materials, and in process solutions. When performing analysis, gold(III) is sorbed from hydrochloric acid solutions with ion-exchanger AB-17, on which rhodanine is preliminarily fixed via chemisorption, after which gold(III) is determined in solid phase.
EFFECT: increased reproducibility and accuracy in individual determination in the form of express-analyses due to fuller extraction gold from solutions thanks to increased sorption capacity.
