FIELD: chemistry.
SUBSTANCE: composition is a composition based on a derivative of antipyrine and organic acid: water-mineral acid-diantipirilmetan (DAM)-derivative of sulfonic acid, wherein as the sulfonic acid derivative contains sodium lauryl sulfate and its molar ratio with DAM varies from 1:1.5 to 7:13 with a total number of 2.0 mmol with an optimal concentration of hydrogen ions in the composition in the range of 0.2-0.5 mol/l.
EFFECT: producing a composition containing low-toxic, biodegradable components, ensuring the improvement of working conditions, safety and cost reduction in the extraction of metal ions from acidic solutions.
