Description
Известны апособы очистки алюМйнатных растворов от примесей ванади , фосфора и органических соединений путем введени в маточный раствор кальцийсодержащей добавки, например окиси кальци . Причем добавку ввод т на разных стади х технологического процесса. Дл очистки от ванади - до или гаосле декомпозиции; дл очистки от органичеоких соединений -после вьгпарки; при этом степень очистки недостаточна.There are known methods for cleaning aluminum solutions from impurities of vanadium, phosphorus and organic compounds by introducing into the mother solution a calcium-containing additive, such as calcium oxide. Moreover, the additive is introduced at different stages of the technological process. To clean vanadium - before or after the decomposition; for purification from organic compounds — after evaporation; however, the degree of purification is insufficient.
По предлагаемому способу маточный раствор перемешивают после декомпозиции с добавкой активного тонкодисперсного осадка трехкальциевого гидроалюмината, получаемого в хемосорбционной форме путем сливани растворов алюмината натри и хлористого кальци в гидротермальных услови х.In the proposed method, the mother liquor is mixed after decomposition with the addition of active fine precipitate of tricalcium hydroaluminate obtained in chemisorption form by merging sodium aluminate and calcium chloride solutions under hydrothermal conditions.
Это увеличивает степень Очистки .растворов ,И усавершенсгвует 1процесс,This increases the degree of purification of the solutions, and accomplishes the first process,
Пример. Активный тонкодйсперсный трехКальциевый гидроалюминат ЗСаО AlgOs йолучают, слива 10-20%, растворы алюМИната .натри NaAlO2 и хлористого кальци СаСЦ IB стехиометриЧеском отношении -к конечному продукту и перемешива их в течение 1 - 2,5 час при 85-90° С. Полученный хемосорбент направл ют «а очистку алюминатных растворов после декомпозиции, содержащих (в е/л) ЮОЫагОк; 61А12Оз; 0,15 PgOs; 0,2V205;Example. Three-calcium active hydroaluminate ZSaO AlgOs yoluchut, plum 10-20%, solutions of aluminate. Sodium NaAlO2 and calcium chloride CaCS IB stoichiometry solutions to the final product and mixing them for 1 - 2.5 hours at 85-90 ° C. directing "a cleaning of aluminate solutions after decomposition, containing (in e / l) SOAcc; 61A12Oz; 0.15 PgOs; 0,2V205;
имеющих концентрацию, равную 150-.200 г/л, и каустический модуль 2,8-3,2.having a concentration of 150-.200 g / l, and a caustic modulus 2.8-3.2.
Маточный раствор перемешивают с активньгм осадком хемосорбента, вз того в количестве 50-70 г/л, 2 час ири 80-90° С.The mother liquor is mixed with the active precipitate of the chemisorbent, taken in an amount of 50-70 g / l, 2 hours and 80-90 ° C.
В результате очистки алюминагного раствора образуютс сложные химические соединени типа гидрогранатов ш виде осадка, которые в дальнейшем могут быть использованыAs a result of purification of the aluminagus solution, complex chemical compounds of the type of hydrogrenates are formed, in the form of a precipitate, which can later be used
дл получени соединений фосфора и ванади .to produce phosphorus and vanadium compounds.
Алюминатный расшор содержит лосле очистки 0,002 г/л ванади и 0,003 г/л фосфора. Содержание органических веществ снижаетс IB 1,8-1,9 раза. Способ эффективен, т. к. позвол ет уменьшить содержание примесей ванади и фосфора -в 50-100 раз.The aluminate solution contains 0.002 g / l vanadium and 0.003 g / l phosphorus. The content of organic substances decreases IB 1.8-1.9 times. The method is effective since it allows reducing the content of vanadium and phosphorus impurities by 50-100 times.
