摘要

综述了多氯联苯在极性和非极性的有机溶剂以及水中辐射降解的研究。多氯联苯的辐射降解主要是通过电子俘获实现的，无论辐射源是γ射线还是通过加速器产生的电子束，大多数反应表现为一级或准一级的反应。最终产物主要是联苯和无机氯化物。其次，多氯联苯也会通过和溶剂形成加合物并发生降解脱氯。含氯原子数较多的以及非邻位取代的多氯联苯比较容易发生辐射降解。

Abstract

The paper presents a review of polychlorinated biphenyls(PCBs) radiolysis in polar and nonpolar solvents. The solvated electron capture is the main reaction whether by ,60,Co−γ irradiation or electron beam as the radiation sources. The reactions follow the first or pseudo−first−order kinetics. The products are biphenyls and chloride.
