Photodedgradant for carbamazepine, method and apparatus for degrading carbamazepine

Abstract

The disclosure provides a photodegradant for carbamazepine, a method and an apparatus for degrading carbamazepine, and relates to the technical filed of degradation of organic pollutants. The photodegradant provided by the disclosure includes a composite solution of a persulfate and a sulfite. In the disclosure, ultraviolet (UV), the persulfate (PS) and the sulfite (S(IV)) are combined to degrade carbamazepine, during which hydrogen sulfate (HSO3−) generated by the hydrolysis of sulfite in water participates in the reaction to produce a large amount of SO4⋅− and HO⋅, thus improving the degradation rate and degradation efficiency of carbamazepine. The composite advanced oxidation system, i.e., the ultraviolet/persulfate/sulfite (UV/PS/S(IV)) system, provided by the disclosure has stronger oxidizability than the ultraviolet/persulfate (UV/PS) system and the ultraviolet/sulfite (UV/S(IV)) system, and results in high degradation rate and high degradation efficiency of carbamazepine.
