PROCEDURE FOR EXTRACTION OF CATIONS OF YTTERBIUM FROM WATER SOLUTIONS OF SALTS

摘要

FIELD: metallurgy. ^ SUBSTANCE: procedure consists in ion flotation with utilisation of (surface active substance) SAS as collector of anion type. As a collector there is used dodecyl sodium sulphate with concentration corresponding of stoichiometric of reaction: Me+3+3DS-=Me[DS-]3, where Me+3 is cation of yttebrium, DS- is dodecyl sulphate-ion. Also, ion flotation is performed at pH=8.0-8.5. ^ EFFECT: raised degree of extraction of ytterbium and reduced expenditures for collector. ^ 1 dwg, 1 tbl, 1 ex
