Description
Изобретение может быть использовано дл очистки растворов солей от примесей т желых металлов в производстве люминофоров.The invention can be used to purify salt solutions from heavy metal impurities in the production of phosphors.
Известно получение сорбента из активированного угл марки БАУ и комнлексообразовател , например 8-оксихинолина, путем нанесени последнего на уголь во влажном состо нии .It is known to prepare a sorbent of activated carbon of the BAU brand and a complexing agent, for example 8-hydroxyquinoline, by applying the latter to the coal in a wet state.
С целью увеличени активной поверхности сорбента предлагаетс способ получени сорбента из активированного угл и комплексообразовател , например 8-оксихинолина, состо щего в том, что комплексообразователь нанос т на активированный уголь путем сублимации и нагреванием смеси до температуры 250-300°С при перемешивании.In order to increase the active surface of the sorbent, a method is proposed for obtaining a sorbent from activated carbon and a complexing agent, for example, 8-hydroxyquinoline, in that the complexing agent is applied to activated carbon by sublimation and heating the mixture to a temperature of 250-300 ° C with stirring.
Пример. 22 г активированного угл марки БАУ, очищенного обработкой сол ной кислотой и водой, высушенного в сущильном щкафу и прокаленного при температуре 300°С, смещивают с 1,5 г 8-оксихинолина. Смесь нагревают в течение 30 мин до 250-300°С в закрытом сосуде при интенсивном перемещивании .Example. 22 g of the activated carbon of the BAU brand, purified by treatment with hydrochloric acid and water, dried in a solid oil and calcined at a temperature of 300 ° C, are shifted from 1.5 g of 8-hydroxyquinoline. The mixture is heated for 30 minutes to 250-300 ° C in a closed vessel with intensive movement.
У полученного таким образом сорбента не наблюдаетс вымывани комнлексообразовател , сорбент обладает значительной емкостью по отношению к нримес м т желых металлов в растворах солей CaCl2(NH4)2HPO4. Емкость сорбента (в мг на I г 8-оксихинолина) по отношению к т желым металлам в растворах солей показана в таблице.The sorbent obtained in this way does not show a complexing agent leaching, the sorbent has a significant capacity with respect to heavy metal impurities in solutions of CaCl2 (NH4) 2HPO4 salts. The capacity of the sorbent (in mg per I g of 8-hydroxyquinoline) with respect to heavy metals in salt solutions is shown in the table.
