1one f Известен способ очистки растворов ca-i харного производства путем электродиализа со сбором удал емьйи ионов в концентрирующем растворе и введении в последний реагента, предотвращающего инкрустировакие тиембран.f A known method of purification of ca-i solutions of charny production by electrodialysis with the collection of the removal of ions in a concentrating solution and the introduction into the latter of a reagent that prevents incrustation of tiembranes. Однако при использовании такого способа создаютс  услови , благопри тные дл  образовани  осадков карбонатов и гидроокисей , т, е. инкрустации мембран, что преп т ствует нормальному переносу ионов через мембрану.However, when using this method, conditions are created that are favorable for the formation of carbonate and hydroxide precipitates, i.e. membrane incrustations, which impede the normal transfer of ions through the membrane. Дл  упрощени  процесса и возможности многократного использовани  реагента предлагаетс  реагент вводить в виде комплексона , например натриевой соли этилендиаминотетрауксусной кислоты, образующего с катионами калыш  и магни  растворимые комплексные соединени . При этом концентрирующий раствор должен иметь рН не выше 8. Комплексен следует вводить в количестве О,ОО5-0,О1% по весу концентрирующего раствора. Так как растворимые комплексы Са + и Mg с этилендиаминотетрауксусной кислотой образуютс  приIn order to simplify the process and the reusable use of the reagent, it is proposed to introduce the reagent in the form of a complexone, for example the sodium salt of ethylene diamine tetraacetic acid, which forms soluble complex compounds with cations of magnesium and magnesium. In this case, the concentrating solution should have a pH not higher than 8. The complex should be introduced in an amount of O, OO5-0, O1% by weight of the concentrating solution. Since soluble complexes of Ca + and Mg with ethylenediaminetetraacetic acid are formed during , то требуетс  небольша  концентраци  комплексона, который про вл ет свое действие только в пограничном слое мембран в услови х высокого рН. При этом, образовавшись у мембран, растворимый комплекс распадаетс  в объеме всего концентрата , так как рН его 8. Его можно использовать многократно., then a low concentration of complexone is required, which manifests itself only in the boundary layer of membranes under high pH conditions. At the same time, having formed at the membranes, the soluble complex disintegrates in the volume of the whole concentrate, since its pH is 8. It can be reused. Пример. Продукты сахарного производства , например полусиропы, сульфитированный сок, очищают путем электродилиза . При этом в концентрирующий раствор ввод т комплексен в количестве 0,О10 ,005% к массе концентрирующего раствоа . рН концентрата не должен превышать 8,0. Концентрацию комплексона в концентрирующем растворе поддерживают на уровне О,О1%. Во врем  электродиализа на оверхности мембран осадок не отлагаетс , что подтверждаетс  данными, приведенными в таблице, а именно результатами измерени  величины тока в цепи электродиализатора , работающего в потенциостатическом режиме на доминерализации сульитированного сока с комплексоном.1Example. Products of sugar production, for example, poly-syrup, sulphite juice, are purified by electroilysis. At the same time, complex, in the amount of 0, O10, 005% by weight of the concentrating solution is introduced into the concentrating solution. Concentrate pH should not exceed 8.0. The concentration of the complexone in the concentrating solution is maintained at the level of O, O1%. During electrodialysis, the sediment is not deposited on the surface of the membranes, which is confirmed by the data given in the table, namely, the results of measuring the current in the electrodialysis circuit operating in potentiostatic mode on the dominonization of sulified juice with complexone. 15,015.0 350 350 15,0 350 350 15.0 350 350 15,0 350. 15.0 350. 15,0 350 15.0 350 15,0 350 15.0 350 15,0 35О 15.0 35O 15,015.0 15,0 350 15.0 350 15,0 35О 35О15.0 35O 35O 15,015.0 Предмет «зобретени  1.
