Abstract
Вивчено ефект взаємодії між вісьмома робочими параметрами, які можуть істотно впливати на деградацію трьох органічних барвників, що мають різну структуру (Cibacron зелений, метиленовий синій і метилоранж). Оцінювання ефекту виконано статистично за допомогою скринінгового методу Плакетта-Бермана. Придатність моделі перевірено з визначенням коефіцієнта R2. Проаналізовано та проілюстровані параметри процесу, які вплинули на ефективність деградації барвників; найважливіші значення (p та F) для трьох барвників довели придатність моделі. Показано, що отримані результати взаємодії параметрів дають можливість виділити ключовий фактор для підвищення ефективності процесу Фентона.
The interaction effect of eight operating factors on the degradation of three organic dyes of different structures (Cibacron green, methylene blue and methyl orange) has been studied. Effect had been evaluated statistically using the Plackett-Burman screening design which ex-tracted valuable information on the most important parameters and their interactions. The goodness of the model fit was checked by the determination of the coefficient R2. The process factors, which affected the degradation efficiency of dyes, were then analyzed and illustrated; the most important valuei (p and F) for three dyes proved the validity of the model. The results of interactions between the factors allow to understand and study the impact of each parameter on the elimination of dyes and to distinguish the key factor to upgrade the efficiency of the Fenton process.
