| description | Constructing a chemical oxidation-reduction synchronous synergistic reaction system may have higher organic matter degradation efficiency compared to the separate operation of oxidation or reduction. By irradiating a mixed solution of sodium persulfate and sodium sulfite with a ultraviolet light (UV), we construct a redox synchronous reaction system for the deep degradation of typical halogenated organic pollutant tribromophenol (TBP), and optimize the main influencing factors of the synergistic reaction system, and then analyze the concerned mechanism. The results show that the new UV-sodium persulfate-sodium sulfite redox system has stronger degradation and debromination efficiency than those of the single UV irradiation, UV-sodium persulfate oxidation system, and UV-sodium sulfite reduction system. In the neutral reaction system with Sodium persulfate and Sodium sulfite dosage of 1.0 mmol/L and pH = 7.0, the removal rate of TBP at 5.0 mg/L within 1 hour is over 99.9% and the debromination rate is 83.9%. The free radical detection results further verifies the significant coexistence mechanism of redox effect in the reaction system. This study provides a new degradation method and technical ideas for the deep removal of typical halogenated new pollutants. |
