Влияние кислотной активации бентонита в составе биполярной мембраны на характеристики электродиализной конверсии сульфата натрия
Аннотация
Изучено влияние на характеристики процесса электродиализа кислотной активации бентонита, входящего в катионообменный слой экспериментальной биполярной мембраны, полученной путем нанесения на анионообменную мембрану-подложку МА-41 жидкого катионообменного слоя ЛФ-4СК, содержащего частицы бентонита.
Кислотная активация бентонита осуществлялась азотной кислотой (С = 1 и 4 моль/дм3) в течение 6 часов, при температурах 20 и 90 °C. Проведена конверсия сульфата натрия (С = 0.5 моль/дм3) в шестисекционном электродиализном аппарате с экспериментальными биполярными мембранами, содержащими бентонит в исходном виде и после кислотной активации. Показано, что добавление в катионообменный слой биполярной мембраны бентонита, обработанного азотной кислотой (C = 4 моль/дм3, t = 90 °C, t = 6 ч), приводит к увеличению производительности, выхода по току и снижению энергетических затрат по сравнению с мембраной, содержащей бентонит в исходном виде.
Экспериментальные биполярные мембраны, изготовленные на основе МА-41 и жидкого сульфокатионообменника, содержащего кислотно-активированные бентонитовые глины, позволяют получить производительность по кислоте и щелочи, сопоставимые с биполярной мембраной МБ-3.
