Электролиз проведен, в несколько стадий, на каждой из которых варьировалась скорость потока, температура .электролита и анодна плотность тока. Варьирование параметров на отдельных стади х электролиза в технологическом процессе осуществл етс при переходе от одного электролизера к другому. При этом каждый электролизер работает в посто нном режиме.and 60 g / l; a solution of 3-150,4, 25.2 and 121 g / l, respectively. The electrolysis was carried out in several stages, at each of which the flow rate, electrolyte temperature, and anode current density varied. The variation of parameters at separate stages of electrolysis in the process is carried out during the transition from one electrolyzer to another. In addition, each electrolyzer operates in a constant mode.
Результаты опытов приведены в таблице.The results of the experiments are given in the table.

Сокращение длительности процесса, пропорциональное увеличению плотности тока, позвол ет сократить потери КМпО за счет реакции гидролиза. ПредлагаемыйThe time average of the current density is 5-8 times the current density used in the known methods, and at the initial stage of electrolysis. Reducing the process time, which is proportional to the increase in current density, reduces the loss of KMpO due to the hydrolysis reaction. Proposed
