FIELD: analytical methods.
SUBSTANCE: invention aims at determining gold(III) in aqueous solutions, in particular in effluents and production solutions. To that end, indicator composition for determining gold(III), which contains anionite AN-25 as sorbent, 2.0%, tin(II) as reagent, 10%, and water, sorbent is preliminarily saturated with gold(III) thiocyanate complexes.
EFFECT: enabled determination of gold(III) using harmless solvents and reduced determination time.
