Фото-Фентон деградация метилового оранжевого с использованием гетерогенных катализаторов на основе полифенилферросилоксана
Аннотация
Исследование относится к актуальному направлению использования эффективных окислительных процессов для деградации органических загрязнителей сточных вод. Синтезированы образцы полифенилферросилоксана и композиты на основе биогенного диоксида кремния, получаемого из рисовой шелухи, и полифенилферросилоксана с различным соотношением. Наличие функциональных групп на поверхности композитов исследовано методом ИК-спектроскопии. Исследована каталитическая активность полученных образцов в реакции деградации метилового оранжевого (рН = 6,8) в условиях УФ-облучения и в присутствии пероксида водорода. Показано, что композит с соотношением полиферрофенилсилоксана к диоксиду кремния, равном 1 : 1, отличается высокой каталитической активностью и стабильностью работы в реакции деградации метилового оранжевого в условиях эксперимента. Данный материал может быть использован как недорогой и экологичный Фентон-подобный катализатор для очистки сточных вод от стойких органических загрязнителей.
