Description
щенного от ионов хлора раствора сернокислой соли металла, промывают водой и реге .нерируют 0,25-2,0 н. водным раствором серной кислоты. При необходимости анионит перевод т в г.идроксильную форму известными приемами. В результате регенерации анионит отмывают от поглощенного хлорид-иона и подготавливают к следующему циклу сорбции .The solution of the sulfate of the metal, which is puffy from chlorine ions, is washed with water and recalculated. 0.25-2.0N. an aqueous solution of sulfuric acid. If necessary, the anion exchange resin is converted into a hydroxyl form by known techniques. As a result of the regeneration, the anion exchange resin is washed from the absorbed chloride ion and prepared for the next sorption cycle.
Пример 1. 1 г сухого анионита АВ-27 в сернокислой форме контактируют в статических услови х с 100 мл раствора сернокислой соли металла концентрацией 1 моль/л с примесью 0,1 г-ион/л хлорид-иона при рН 3-5. Емкость анионнта по хлору составл ет дл сульфата натри 1,52 мг-экв/г, сульфата цинка 2,14 мг-экв/г, сульфата кадми 1,28 мгэкв/г , сульфата меди 1,35 мг-экв/г, сульфата кобальта 1,35 мг-экв/г, сульфата никел 1,82 мг-экв/г. При пропускании через насыщенный хлором анионит АВ-27 10 объемов водного раствора серной кислоты концентрацией 25,0 г/л степень десорбции хлора составл ет 97-98%.Example 1. 1 g of dry anion exchanger AB-27 in sulphate form is contacted under static conditions with 100 ml of a 1 mol / l sulphate solution of a metal with an impurity of 0.1 g-ion / l of chloride ion at a pH of 3-5. Chlorine capacity of the anionnt is 1.52 meq / g for sodium sulfate, 2.14 meq / g for zinc sulfate, 1.28 mg eq / g for cadmium sulfate, 1.35 meq / g for copper sulfate, cobalt 1.35 meq / g, nickel sulfate 1.82 meq / g. When AB-27 anion exchanger, saturated with chlorine, passes through 10 volumes of an aqueous solution of sulfuric acid at a concentration of 25.0 g / l, the degree of chlorine desorption is 97-98%.
Пример 2. Сорбцию осуществл ют в статических услови х на анионите АВ-27 в гидроксильной форме из растворов с концентрацией сульфата цинка 1 моль/л, хлорида натри 0,1 моль/л и серной кислоты от О до 0,2 моль/л при объемном соотношении ионит: :раствор, равном 1: 10. Емкость анионита по хлору составл ет 1,81 -1,43 мг-экв/г.Example 2. Sorption was carried out under static conditions on anion exchanger AB-27 in hydroxyl form from solutions with a zinc sulfate concentration of 1 mol / l, sodium chloride 0.1 mol / l and sulfuric acid from 0 to 0.2 mol / l with the volume ratio of ion exchanger:: solution is 1:10. The capacity of the anion exchanger for chlorine is 1.81-1.43 mg eq / g.
Пример 3. В динамических услови х очищают раствор сернокислой соли цинка концентрацией 1 моль/л с примесью 0,1 моль/л хлорида натри сорбцией на анионите АВ-27 в сернокислой форме. Степень очистки растворов от хлора составл ет 98% при динамической обменной емкости анионита -по хлору 2,36 мг-экв/г.Example 3. Under dynamic conditions, a solution of 1 mol / l zinc sulfate with admixture of 0.1 mol / l of sodium chloride by sorption on AB-27 anion exchanger in sulfate form is purified. The degree of purification of solutions from chlorine is 98% with a dynamic exchange capacity of the anion-exchange resin 2.36 mg eq / g for chlorine.
