Изобретение относитс  к способам очистки растворов селена от примесей т желых металлов и может быть использовано, например, в гидрометаллургии селена.The invention relates to methods for purifying selenium solutions from heavy metal impurities and can be used, for example, in selenium hydrometallurgy.

Известен способ очистки растворов селена от примесей т желых металлов путем их экстракции трибутилфосфатом или триоктиламином в две стадии в присутствии добавок хлор-ионов.A known method of purification of selenium solutions from heavy metal impurities by their extraction with tributyl phosphate or trioctylamine in two stages in the presence of chlorine ions.

Недостатком этого способа  вл етс  его сложность (он двустадиен; кроме того, в исходный раствор необходимо вводить серную и сол ную кислоты), а также недостаточна  эффективность очистки исходного раствора.The disadvantage of this method is its complexity (it has two stages; in addition, it is necessary to introduce sulfuric and hydrochloric acid into the initial solution), as well as the insufficient purification efficiency of the initial solution.

С целью упрощени  процесса и повышени  эффективности очистки экстракцию ведут растворами галоидных солей четвертичных аммониевых оснований в углеводородах, содержащими добавки трибутилфосфата или высокомолекул рного спирта.In order to simplify the process and increase the efficiency of purification, extraction is carried out with solutions of quaternary ammonium halide salts in hydrocarbons containing additives of tributyl phosphate or high molecular weight alcohol.

Согласно изобретению, целесообразно добавки трибутилфосфата или высокомолекул рного спирта вводить в количестве 10- 30%.According to the invention, it is expedient to add additives of tributyl phosphate or high molecular weight alcohol in an amount of 10-30%.

При осуществлении способа достигаетс  упрощение процесса (экстракцию осуществл ют непосредственно из исходного раствора), а также повышение эффективности очистки (достаточно 1-2 ступеней экстракции).By implementing the method, a simplification of the process is achieved (extraction is carried out directly from the initial solution), as well as an increase in the cleaning efficiency (1-2 extraction steps are sufficient).

Пример. Раствор, полученный при выщелачивании селено-мышь кового кека и имеющий состав, в г/л:Example. The solution obtained by leaching of selenium-mouse cake and having a composition in g / l:
