FIELD: analytical methods.
SUBSTANCE: invention is designed for analysis of gold-containing industrial and natural objects. Method resides in catalytic effect of gold on potassium permanganate-mediated diphenylamine oxidation kinetics at pH 2-7. Concentration of gold is determined as reaction time reciprocal value.
EFFECT: lowered determination susceptibility threshold.
