In this study, the effectiveness of pH (1-5), hydrogen peroxide concentration (5-10 mM), ion Fe2+ concentration (0,1-0,5 mM), and reaction time on treatment of mononitrotoluen by homogeneous Photo-Fenton process was evaluated. The response surface methodology (RSM) was applied to design the experiment and determine the optimal treatment. The results indicated, at optimized pH=3, C0MNT=100 mg/L, CFe2+= 0.4 mM, CH2O2= 2.5 mM, the MNT treatment efficiency reached 99.4% after 5 minutes.
