Description
Способ получени алюминиевой соли этилендиаминтетрауксусной кислоты с помощью катионита, предварительно переведенного в «алюминиевую форму, известен.The process for the preparation of the ethylenediaminetetraacetic acid aluminum salt by means of a cation exchanger previously converted into an aluminum mold is known.
Сущность предложенного способа заключаетс в подборе вымывающего раствора, представл ющего собой трехзамещенную натриевую соль этилендиаминтетрауксусвой кислоты, имеющего ,0, что преп тствует выпадению кристаллов самой кислоты в смол ном слое. Предлагаемый способ вл етс новым и решает серьезную задачу предотвращени от забивани катионитового сло осадком, что открывает возможность- дл его промышленного использовани . Технологический процессThe essence of the proposed method lies in the selection of an elution solution, which is a trisubstituted sodium salt of ethylene diamine tetraacetic acid, having 0, which prevents the acid crystals from precipitating in the resin layer. The proposed method is new and solves the serious problem of preventing sediment from clogging the cation layer, which opens up the possibility for its industrial use. Technological process
Алюминиева соль этилендиаминтетрауксусной кислоты (HA1EDTA) успещно примен етс в качестве вымывающего раствора при разделении редкоземельных элементов иттриевой группы.Ethylene diamine tetraacetic acid (HA1EDTA) aluminum salt is successfully used as a washout solution in the separation of rare earth elements of the yttrium group.
Раствор НА1ЕДТА необходимой концентрации можно приготовигь методом ионного обмена.A HAIEDTA solution of the required concentration can be prepared by ion exchange.
Процесс проходит в несколько стадий:The process takes place in several stages:
1)Сорбци . Через катионит в водородной или другой форме пропускают 5-7%-ный раствор алюминиевой соли: А1(С1)з, А1(ЫОз)з и т. д. и перевод т смолу в алюминиевую форму1) Sorbtsi. A 5-7% solution of aluminum salt is passed through a cation exchanger in hydrogen or another form: A1 (C1) h, A1 (NO3) h, etc., and the resin is converted into aluminum form
2)Промывка. Удаление свободной соли и кислоты.2) Flushing. Removal of free salt and acid.
3)Десорбци алюмини раствором три л она Б. Концентраци раствора по трилону Б определ етс требовани ми последующего процесса делени . Значение ,0 устанавливаетс при добавлении водного аммиака или едкого натра3) Desorption of aluminum with a solution of three liters. The concentration of the Trilon B solution is determined by the requirements of the subsequent division process. A value of 0 is set by adding aqueous ammonia or caustic soda.
