Abstract

Для комбинированного получения пероксодисульфата натрия и раствора едкого натра из сульфата натрия проводится электролиз, который проходит в двухкамерной электролизерной ячейке с разделенными катионообменной мембраной катодными и анодными пространствами, температура электролиза устанавливается равной 30-70°С, раствор сульфата натрия насыщен при этой температуре по меньшей мере на 75%, концентрация ионов натрия поддерживается в пространстве от 4,5 до 6,0 моль/л, а из цикла из катодного пространства выводится раствор едкого натра.Международная заявка была опубликована вместе с отчетом о международном поиске.
