The wastewater containing Mononitrotoluene (MNT) has adverse effects on human health, living organisms, and the surrounding environment. In this study, the efficiency of MNT treatment in water using the Sono-Photo-Fenton-like process combined with zero-valent iron nanoparticles (nZVI) was evaluated. The effects of pH, H2O2 concentration, nZVI concentration, and reaction time on the treatment efficiency were investigated using experimental design through the Response Surface Methodology (RSM). The study results showed that the treatment efficiency of MNT using the Sono-Photo-Fenton process combined with nZVI reached 100% under the conditions of pH = 2, initial MNT concentration of 100 mg/L, nZVI concentration CnZVI = 0.5 mM, CH2O2 = 5 mM and a reaction time of 30 minutes.
