METHOD OF EXTRACTING SAMARIUM (III) CATIONS

摘要

FIELD: chemistry.SUBSTANCE: invention relates to extraction of substances with organic extractants from aqueous solutions, particularly a method of obtaining samarium (III) cations from impoverished or industrial material using a liquid extraction technique. The method of extracting samarium (III) cations involves liquid extraction using an extractant - isooctyl alcohol and an organic diluent in form of sodium dodecylsuphate in a concentration which corresponds to stoichiometry. Extraction is carried out at pH=3.0-6.0.EFFECT: invention enables to achieve 90% extraction of samarium (III) cations in aqueous solutions of salts thereof.1 dwg
