In this study, the effects of four main factors on the removal of absorbable organic halogens were evaluated by response surface methodology, and the changes of absorbable organic halogens components were characterized by gas chromatography-mass spectrometer during the Fenton reaction. The high regression coefficient (R2 = 0.9028) and the low coefficient of variation (7.45%) indicated that the model was accurate in predicting the experimental results. The optimized pH, Fe2+ concentration, molar ratio of H2O2/Fe2+ and reaction time were respectively 3.4, 16.3 mM, 22.5 and 1.2 h. Consequently, 93.8% of absorbable organic halogens were removed under the optimized condition. The initial pH is the most important factor impacting the absorbable organic halogens removal. Furthermore, gas chromatography-mass spectrometer revealed that 25 out of 28 organic compounds including 7 absorbable organic halogens were thoroughly removed. Conclusively, Fenton reaction can effectively remove absorbable organic halogens from the simulated bleaching effluent.
