METHOD FOR EXTRACTION OF PALLADIUM FROM WATER SOLUTIONS OF METAL SALTS Russian patent published in 2016 - IPC B01D11/04 C22B3/26 C01G55/00

Abstract RU 2574266 C1

FIELD: chemistry.

SUBSTANCE: method for extraction of palladium from water solutions of metal salts includes extraction of palladium from hydrochloric acid water solutions and re-extraction with 8-12% hydrochloric acid solution of thiourea. Prop-2-inyltrioctylammonium bromide in toluene is used as extragent, interval of phase contact time is set within 4-6 min, and ratio of phase volumes is set as equal 1:1.

EFFECT: increased degree of palladium extraction from hydrochloric acid solutions during one cycle of extraction with toluene solutions of prop-2-inyltrioctylammonium bromide and increased degree of palladium re-extraction.
