Description
Известен снособ электрохимического выделени гидрата окиси алюмини из алюмипатных растворов. Известно получение гидроокиси алюмини из алюминатных растворов в электролизерах с чейками и диафрагмами, а также применение перфорированпых электродов из никел и стали дл электролиза алюмипатных растворов.A known method for the electrochemical separation of alumina hydrate from aluminate solutions. It is known to produce aluminum hydroxide from aluminate solutions in electrolyzers with cells and diaphragms, as well as using perforated nickel and steel electrodes for the electrolysis of aluminate solutions.
Дл ускорени и обеспечени непрерывности процесса предлагаетс исходный алюминатный раствор подвергать последовательному электролизу при нлотности тока 0,075- 0,1 а/ж в многокамерных электролизерах с катионообменными диафрагмами, изготовл емыми из ионообменных смол на основе полиэтилена.In order to accelerate and ensure the continuity of the process, it is suggested that the initial aluminate solution be subjected to sequential electrolysis with a current density of 0.075-0.1 a / f in multi-chamber electrolyzers with cation-exchange diaphragms made of polyethylene-based ion exchange resins.
Сущность способа заключаетс в том, что электролиз алюмпиатиых растворов нроизво;| , т в многокамерных электролизерах, в которых анодные и катодные пространства разделены катпонообменной диафрагмой. Плотность тока нри электролизе 0,075-0,1 а/лга.The essence of the method lies in the fact that the electrolysis of aluminae solutions is not functional; | , T in multi-chamber electrolyzers, in which the anode and cathode spaces are separated by a cathode-exchange diaphragm. The current density in the electrolysis of 0.075-0.1 a / log.
В качестве диафрагм, 1.с ользу1отс мсМбра л из ио 1ообменно | смолы КУ-2 ia осH0 je полиэтилена.As diaphragms, 1.c. With the use of msMbrl from io 1 exchange | resins KU-2 ia oc H0 je polyethylene.
Анодом служит перфор :рова ип Й никель, катодом - нерл авеюща перфорированна сталь.The anode is a perforation: a groove of a nickel, and a cathode — nerve perforated steel.
В катодное пространство поступает 5%-ный раствор щелочи (NaOH), а в анодное - раствор алюмината натри .A 5% alkali solution (NaOH) enters the cathode space, and sodium aluminate solution enters the anode space.
