Description
Известен способ удалени ртути из ее минеральных растворов с немощью железа или меди. Дл удалени ртути из растворов сульфокислот антрахинона этот способ не примен лс из-за возможности восстановительного действи железа или меди на антрахинонсульфокислоту .There is a known method of removing mercury from its mineral solutions with the weakness of iron or copper. To remove mercury from solutions of anthraquinone sulfonic acids, this method was not used because of the possibility of the reducing effect of iron or copper on anthraquinone sulfonic acid.
Согласно изобретению предложен способ, по которому ртуть удал етс из антрахинон-1-сульфокислоты с помощью железа или меди, вводимых в виде стружки. При этом ртуть выдел етс в виде тонкодисперсного осадка.According to the invention, a method is proposed in which mercury is removed from anthraquinone-1-sulfonic acid with iron or copper, introduced as chips. In this case, mercury is released as a fine sediment.
Особенность способа заключаетс в том, что он примен етс дл растворов антрахинон-1-сульфокислоты в разбавленной серной кислоте при температуре не выше 60°.A feature of the method is that it is used for solutions of anthraquinone-1-sulfonic acid in dilute sulfuric acid at a temperature not higher than 60 °.
Дл фильтрации реакционной массы примен ют фильтр, состо щий из кислотостойких непроницаемых дл тонкодисперсных осадков элементов , например, фторопластовых или керамиковых «свечей.For filtering the reaction mass, a filter is used consisting of acid-resistant impermeable to finely dispersed precipitation elements, for example, fluoroplastic or ceramic candles.
Пример. В 200 г раствора антрахинон-1-сульфокислоты в разбавленной сер«ой кислоте (не выше 20%), подогретого до 50-60°, постепенно ввод т при перемешивании железо или медь в виде стружки в количестве , близком к теоретическому - требуемому. Спуст 30 минут, вс ртуть выдел етс в виде тонкодисперсного осадка. После фильтрации реакционна масса практически свободна от ртути.Example. In 200 g of a solution of anthraquinone-1-sulfonic acid in dilute sulfuric acid (not higher than 20%), heated to 50-60 °, iron or copper in the form of chips, in a quantity close to the theoretical value, is gradually introduced with stirring. After 30 minutes, all of the mercury is released as a fine precipitate. After filtration, the reaction mass is practically free from mercury.
