Изобретение относитс к области цветной металлургии, в частности к получению титансодержащего сорбента термическим путем, примен емого дл выделени некоторых элементов из кислых растворов.The invention relates to the field of non-ferrous metallurgy, in particular to the preparation of a titanium-containing sorbent by thermal means, used to separate some elements from acidic solutions.
Известен способ получени титансодержащих сорбентов, основанный на гидролитическом взаимодействии солей титана с соответствующими осадител мп. Однако при осуществлении известного способа необходимо применение растворов солей титана и использование дорогосто щих осадителей. Кроме этого, фильтрование полученных объемных осадков весьма затруднено.A known method for producing titanium-containing sorbents, based on the hydrolytic interaction of titanium salts with the corresponding precipitator MP. However, the implementation of this method requires the use of solutions of titanium salts and the use of expensive precipitating agents. In addition, filtering the obtained bulk precipitation is very difficult.
Дл обеспечени селективности сорбента по отнощению к мышь ку и сурьме предложен способ получени сорбента на основе соединений титана путем смешени гидратированной двуокиси титана или метатитановой кислоты с серной кислотой с последующей термообработкой высушенного продукта с весовым соотношением от 1:0,45 до 1:1,83 при 200- 250°С в присутствии солей аммони .To ensure sorbent selectivity with respect to arsenic and antimony, a method was proposed for preparing a sorbent based on titanium compounds by mixing hydrated titanium dioxide or metatitanic acid with sulfuric acid, followed by heat treatment of the dried product with a weight ratio of from 1: 0.45 to 1: 1.83 at 200-250 ° C in the presence of ammonium salts.
Пример 1. 400 г влажной гидратированной двуокиси титана, содержащей 30% воды и 6% хлористого аммони , смешивают с концентрированной серной кислотой (техн., уд. вес 1,83) и спекают в муфеле при 200°С в-течение 5 час.Example 1. 400 g of wet hydrated titanium dioxide containing 30% water and 6% ammonium chloride are mixed with concentrated sulfuric acid (tech., Specific weight 1.83) and sintered in a muffle at 200 ° C for 5 hours.
Сорбционна способность полученного твердого продукта по мыщь ку - 60-80%, по сурьме -90-97%.The sorption capacity of the obtained solid product in the mouse is 60–80%, in antimony it is 90–97%.
Пример 2. 200 г воздушно-сухой метатитановой кислоты (Н2Т1Оз или TiO2-H2O) спекают при 200°С с серной кислотой.Example 2. 200 g of air-dry metatitanic acid (H2T1Oz or TiO2-H2O) are sintered at 200 ° C with sulfuric acid.
Сорбционна способность полученного твердого продукта по мышь ку - 65-91,8%, по сурьме -91,8-93%.The sorption capacity of the obtained solid product by mouse is 65–91.8%, and antimony –91.8–93%.
Сорбенты могут быть регенерированы обработкой щелочным или содовым раствором с последующим спеканием с серной кислотой и возвращены в процесс.Sorbents can be regenerated by treatment with an alkaline or soda solution, followed by sintering with sulfuric acid and returned to the process.
