Abstract
Способ извлечения ионов эрбия из раствора, включающий ионную флотацию с использованием в качестве собирателя додецилсульфат натрия в концентрации, соответствующей стехиометрической реакции ! Me+3+3DS-=Me[DS-]3, ! где Me+3 - катион металла, DS- - додецилсульфат-ион, отличающийся тем, что в качестве извлекаемых ионов используют соли эрбия, при этом для максимального извлечения эрбия ионную флотацию осуществляют при pH=6,4. A method of extracting erbium ions from a solution, including ion flotation using sodium dodecyl sulfate as a collector in a concentration corresponding to the stoichiometric reaction! Me + 3 + 3DS- = Me [DS-] 3,! where Me + 3 is a metal cation, DS- is a dodecyl sulfate ion, characterized in that erbium salts are used as recoverable ions, while ion flotation is carried out at pH = 6.4 to maximize erbium extraction.
