| 摘 要： | 多氯联苯(PCBs)已成为全球性污染物,在人类生存的各种环境因素中,包括空气、水体、土壤、生物体,甚至远离大陆的海洋中已都发现PCBs的存在.自从发现PCBs能吸收190—240nm和280—310nm紫外光以来,人们推断PCBs吸收阳光中的紫外线后的光降解可能是从环境中除去PCBs的一种有效途径.因此对PCBs的光降解

| Abstract: | The photodegradation of trace tetrachlorobiphenyl(TCB) in water was carried out and compared with those in hexane. Dechlorina-tion processes during the photodegradation of TCB in water were observed and the photoproducts were identified by GC retention time and GC-MS. The photodegradation rate of TCB in water was 2?3 times slower than that in hexane. |
