STUDIES ON PHOTODEGRADATION OF TETRACHLO ROBIPHENYL IN WATER AND IN HEXANE BY GC-MS
水和正已烷中痕量四氯联苯光降解研究

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.
