ЭЛЕКТРОХИМИЧЕСКАЯ ОЧИСТКА СТОЧНЫХ ВОД, СОДЕРЖАЩИХ АЗОБЕНЗОЛ
Аннотация
Исследована возможность применения электрохимической обработки для обезвреживания сточных вод, содержащих азобензол. Особенное внимание уделено идентификации продуктов восстановления и окисления азобензола. Показано, что электрохимическое восстановление может приводить к образованию токсичных бензидинов, в то время как продуктами электрохимического окисления являются полифенолы, что более приемлемо с экологической точки зрения.
