Description
Промышленный каустик, получаемый ртутным методом, ие обладает степенью чистоты, котора предъ вл етс к продукту, используемому, например , в производстве полупроводников, высокопрочного корда и дл других целей.The industrial caustic produced by the mercury method does not have a degree of purity that is applied to the product used, for example, in the manufacture of semiconductors, high strength cord and for other purposes.
Описываемый способ очистки растворов каустической соды от примесей ртути, железа и т желых .еталлов, сероводородной группы позвол ет получить продукт, содержание пpи receй в котором снижаетс по железу до 2,, по т желым металлам до и по ртути до . Это достигаетс тем, что очистку осупюствл ют электроосмотическим .The described method of cleaning solutions of caustic soda from impurities of mercury, iron and heavy metals, hydrogen sulfide groups allows to obtain a product, the content of which in iron decreases to 2, for heavy metals and mercury to. This is achieved in that the purification is performed by electroosmotic.
Способ осуществл ют следующим образом.The method is carried out as follows.
Коицентрированную каустическую соду, подлежащую очистке, непрерывно пропускают через электролизер между никелевыми электродами, отделенными пористыми диафрагмами от среднего пространства, в котором движетс раствор каустической соды. Около iSVo раствора фильтруетс через диафрагмы и выводитс из катодного и анодного иространсгв в виде загр зненного каустика (с повышенным содержанием примесей), а остальное количество раствора представл ет собою очищенный каустик и выводитс из межэлектродного пространства.The centered caustic soda to be cleaned is continuously passed through an electrolytic cell between nickel electrodes separated by a porous diaphragm from the middle space in which the caustic soda solution is moving. Around the iSVo solution is filtered through the diaphragms and removed from the cathode and anode and spreads in the form of contaminated caustic (with a high content of impurities), and the remaining amount of the solution is the purified caustic and is removed from the interelectrode space.
Процесс ведетс при 90°; объемна плотность тока 60 а/л; расход электроэнергии 0,2 квт-( на литр очиш;енного каустика концентрациеГ 600 г/л NaOH. Электроос.мотический процесс сопровождаетс электролизом воды с выделением водорода и кислорода из крайних чеек электролизера .The process is conducted at 90 °; bulk current density 60 a / l; Electricity consumption 0.2 kW- (per liter of cleaned caustic concentration 600 g / l NaOH. Electroosmotic process is accompanied by electrolysis of water with evolution of hydrogen and oxygen from the extreme cells of the electrolyzer.
