Fenton-like reaction, Triclocarban, Iron-powderAbstract
The objective of this study was to the feasibility for Triclocarban degradation using Fenton-like process. The effects of hydrogen peroxide concentration, and initial pH of solution were investigated. The initial concentration of triclocarban, the reaction time were kept constant and catalyst loading (iron-powder) of 40 ppm, 240 min and 1.6 g L-1, respectively. Optimal conditions were determined to be pH 7, hydrogen peroxide 50 mM, triclocarban 40 ppm . The optimal pH was found to be 7 and triclocarban degradation efficiency removal was 78% within 240 min. These promising results clearly demonstrate the potential of the heterogeneous Fenton-like process for the effective degradation of triclocarban by iron-powder. The kinetic analysis implied that the reaction followed pseudo first order kinetics. It’ s apparent rate constant is calculated to be 3.8 × 10-3 min-1.
