Изобретение относитс  к способу очистки растворов от сульфатов и может найти применение в алюминиевой промышленности при очистке анодных газов и регенерации фторсолей .The invention relates to a method for the purification of solutions from sulphates and can be used in the aluminum industry for the purification of anode gases and the regeneration of fluorides.

Известен способ удалени  сульфатов из растворов щелочными сол ми низкомолекул рных карбоновых кислот с числом атомовA known method of removing sulfates from solutions of alkaline salts of low molecular weight carboxylic acids with the number of atoms

ClCIQ.ClCIQ.

Однако из растворов фторсолей с)льфаты с помощью указанных щелочных солен карбоиовых кислот не удал ютс .However, from solutions of fluorine salts c), the compounds are not removed with the aid of the indicated alkaline salts of carboxylic acids.

С целью очистки растворов фторсолей, например фтористого патри , предлагаетс  производить очистку с помощью солей высокомолекул рных карбоновых кислот с числом атомов углерода Cis-€29.For the purpose of purification of fluorosol solutions, for example, patric fluoride, it is proposed to purify with the help of salts of high molecular weight carboxylic acids with the number of carbon atoms Cis- € 29.

В качестве солей карбоновых кислот целесообразно использовать кубовые остатки производства высших жирных кислот и спиртов, вводимых в количестве 20-100 г/м раствора.As salts of carboxylic acids, it is advisable to use the bottoms of the production of higher fatty acids and alcohols, introduced in the amount of 20-100 g / m solution.

Предлагаемый способ позвол ет снизить содержание сульфатов в растворе с 70-90 г/л до 15-25 г/л.The proposed method allows reducing the sulfate content in the solution from 70-90 g / l to 15-25 g / l.

Пример. В содовый раствор газоочистки концентрацией по NagCOs 30-40 г/л ввод т кубовые остатки производства высших жирных кислот спиртов в количестве 1,5-2 л на 240 м. При этом содержание сульфата натри  снижаетс  с 70-90 г/л до 15- 25 г/л.Example. In the soda solution of gas purification with a concentration of 30–40 g / l of NagCOs, bottoms from the production of higher fatty acids of alcohols in the amount of 1.5–2 l per 240 m are introduced. At that, the content of sodium sulphate is reduced from 70–90 g / l to 15– 25 g / l.
