Изобретение . относитс к ионообменному выделению рубиди из смесей с калием.The invention. refers to the ion-exchange release of rubidium from mixtures with potassium.
Известен способ выделени рубиди из смесей с калием непрерывным противоточным ионным обменом путем сорбции смеси ионов рубиди и кали из раствора в одной колонне и вытеснени сорбированной смеси из ионита во второй колонне. Недостатком известного способа вл етс необходимость регенерации ионита, т. е. перевода ионита из Ва-формы в Н-форму, перед повторным использованием. Регенерацию осуществл ют в отдельной колонне , н она требует значительных затрат реактивов .A known method for the separation of rubidium from mixtures with potassium by continuous countercurrent ion exchange by sorption of a mixture of rubidium and potassium ions from a solution in one column and displacing the sorbed mixture from an ion exchanger in the second column. The disadvantage of the known method is the necessity of regeneration of the ion exchanger, i.e. the transfer of the ion exchanger from the Ba-form to the H-form, before reuse. The regeneration is carried out in a separate column, and it requires a considerable amount of reagents.
С целью исключени стадии регенерации в предлагаемом способе сорбцию провод т на катионите в аммонийной форме и в качестве вытесн ющего раствора используют раствор соли аммони .In order to eliminate the regeneration stage in the proposed method, the sorption is carried out on the cation exchanger in the ammonium form and the ammonium salt solution is used as the displacement solution.
Получающийс в десорбционной колонне ионнт ЫН4-форме подают в сорбционную колонну , а выход щий из сорбционной колонны раствор соли аммони используют дл вытеснени раздел емых ионов в десорбционной колонне.The H2H4 form ionon obtained in the desorption column is fed to the sorption column, and the ammonium salt solution leaving the sorption column is used to displace the separated ions in the desorption column.
Дл полного вытеснени смеси рубиди и кали ионами аммони соотнощение потоков раствора L и ионита 5 в десорбционной колонне поддерживают таким, чтобыIn order to completely displace the mixture of rubidium and potassium with ammonium ions, the ratio of the flows of solution L and ion exchanger 5 in the desorption column is maintained so that

This, in addition to the separable ionamic solution, contains a certain amount of ammonium non-separable ions. Before feeding this solution into the sorption column, the ammonium salt is completely or partially removed. The removed salt added to the solution used for desorption.

A method for separating rubidium from mixtures with calcium is continuously countercurrent ion exchanged by sorbing a mixture of rubidium and potassium 5 from a solution in one column and displacing 4 sorbed mixture from an ion exchanger in the second column, differing in that, in order to exclude the stage of regeneration of the ion exchanger, sorption is carried out on the cation exchanger in the ammonium form and the ammonium salt solution is used as the displacing solution.
