FIELD: analytical methods.
SUBSTANCE: invention relates to photometric determination of aluminum(III) in solutions of pure salts and artificial mixtures containing aluminum(III) in very low concentration. Method comprises transfer of aluminum(III) into complex compound with aluminon in low-acidic medium: to solution of aluminum(III) with pH 0-2 is added 100-120-fold amount of aluminon, 0.3-0.5 mL of surfactant solution containing 2% of gelatin solution, and water to 10 mL of total volume, after which resulting mixture is heated for 4-6 min on water bath at 80-98°C.
EFFECT: increased sensitivity and selectivity of analysis.
