Reactive dye degradation by a photochemical AOP ; development of a kinetic model for UV/H2O2 process
An application of UV/H_2O_2 process for the treatment of model wastewater containing organic reactive azo dye C.I. Reactive Blue 137 (RB137) was studied. The efficiency of applied process for decolorization and mineralization of RB137 model solution is discussed. The influence of operating process parameters, initial pH and initial concentration of H_2O_2, as well as initial dye concentration on process effectiveness was investigated. Both direct UV photolysis and OH radical attack were assumed as RB137 degradation mechanisms and a detail kinetic model for dye degradation by UV/H_2O_2 process was proposed. Predicted system behavior was compared with experimentally obtained results of decolorization and mineralization of RB137 wastewater. A sensitivity analysis for the evaluation of importance of each reaction used in model development was also included.
