To use the microwave/ML/TiO₂ hybrid system as an advanced treatment of nitrobenzene (NB), a series of experiments were performed to examine the effects of microwave irradiation and auxiliary oxidants. The degradation of NB was carried out using different combinations of five-unit treatment techniques. The NB degradation rate increased with increasing microwave intensity. The circulation fluid velocity, concentration of H₂O₂, and the rate of O₂ gas injection showed the highest rate of degradation under optimal conditions. A significant synergistic effect was observed when H₂O₂ addition was combined with the microwave/ML/TiO₂ hybrid process.
