FIELD: chemistry.
SUBSTANCE: concentration of microelements is carried out for subsequent analytical determination by coprecipitation with diantipyrilmethane forming a water-mineral acid-ammonium thiocyanate-collector dithiocyanate diantipyrylmethanate system. Coprecipitation of microelentics is carried out at the optimum concentration of hydrogen ions in the range of 0.05-2.0 mol/l and thiocyanate ions in the range of 0.05-2.0 mol/l.
EFFECT: decreasing the toxicity and increasing the stability of the anionic background of the aqueous solution to the action of external factors, increasing the extraction efficiency and expanding the list of recoverable metal ions.
