摘要: In view of their biological and chemical stability, the photoreactions of polychlorobiphenyls (PCB's) may be a significant route for their environmental degradation. Reductive dechlorination is the main photoreaction of PCB's in solvents such as hexane,(CROSBY and HAMADMAD, 1971). In more hydroxylic solvents, the rate of dechlorination is faster and'polar'products are also formed,(CROSBY and LEITIS, 1969). The observed PCB photoproducts are all thought to arise through reaction of the same triplet excited state via …
