FIELD: chemistry.
SUBSTANCE: invention relates to a method of extracting silver ions from aqueous solutions and is used in extraction of substances with organic extractants from aqueous solutions and can be used in non-ferrous and ferrous metallurgy, as well as for cleaning industrial and household wastes. Method of extracting silver ions from solution with tributyl phosphate (TBP) includes contacting extractant and solution, mixing, settling and separation of phases. Extraction is carried out from hydrochloric acid solutions with concentration 3 n. HCl and 240 g/dm3 NaCl with addition of TBP in portions at temperature t = 20 °C.
EFFECT: technical result consists in efficiency of extracting silver from aqueous solutions.
