Study of optimal parameters of the H2O2/O3 method for the decomposition of acetic acid

Advanced oxidation processes (AOPs) constitute one of the most effective methods to decompose persistent organic pollutants in water using OH radicals. In this study, the parameters of the H2O2/O-3 method in the decomposition of acetic acid were investigated through a combination of experiments and numerical simulations. A simplified reaction model was built based on the analysis of the decomposition path. The simulation results showed that effective treatment of acetic acid can be achieved when the H2O2 supply rate is half of the O-3 absorption rate as one H2O2 and two O-3 molecules are necessary to produce two OH radicals.
