摘要 综述了近10年以来多氯联苯(PCBs)在有机相、表面活性剂中的直接光化学降解行为,以及PCBs在水相中的光敏化反应和光催化反应等间接光化学降解行为。从光解动力学、光解途径、光解机理以及光解产物等几方面阐述了PCBs的光化学行为,光催化降解有机污染物是一种很有发展前景的有机污染物治理技术。 The advances in recent ten years in the fields of direct photochemical degradation of polychlorinated biphenyls(PCBs) in organic solvents and surfactant as well as indirect photochemical degradation in water including photosensitized reaction and light-catalyzed reaction are reviewed.The photochemical reaction of PCBs is discussed in the respects of photolytic kinetics,pathway,mechanism and products.Photocatalytic degradation of organic pollutants is a promising treatment technology.
