| Abstract |
Aromatic nitro compounds are among the most common industrial pollutants. They are used in inks and dyes, in the pharmaceutical industry and cosmetics, and in explosives. In this article, an experimental electrochemical method for the recycling of effluents contaminated with aromatic nitro compounds is proposed, and the influence of various parameters (temperature, current density, electrolyte concentration) and their interactions on the decomposition of these compounds are studied. A comparative study indicated that these parameters do not influence their degradation in sulfuric acid, while the best results are obtained in sulfuric acid concentrations of 96%. Electrochemical methods represent a viable alternative to biodegradation. |
