Evaluation of atrazine degradation in UV/FeZSM-5/H2O2 system using factorial experimental design
Degradation of atrazine in model wastewater by UV/FeZSM-5/H2O2 system chosen as optimal for application of advanced oxidation process (AOP) has been studied in a batch photo reactor. The statistical study of the process was performed using two-level full factorial experimental design with the three process parameters. Individual parameters and their interaction effects on atrazine degradation were determined and statistical model of process was developed. The optimal operating conditions were established. This approach has also given a broader insight of the processes that were occurring in the reaction system, and it has finally led to simplification in terms of kinetics. Atrazine degradation was described by pseudo-first order kinetics with observed rate constant k′ = 2 × 10− 3 s− 1.
