The photo conversion of parachlorophenol(4-CP) in the presence of ice and nitrite under UV radiation in a temperature range of-14~-12℃ was investigated.According to the results,the conversion of 4-CP in the presence of ice reached 80% within 180 min.Under the conditions mentioned above,four photoproducts:5-chlorobiphenyl-2,4'-diol,phenol,4-(4-chloro-2-nitrophenoxy)phenol and 4-chloro-2-nitrophenol were identified,which was a little different from that of the photoreaction in solution.The presence of nitrite could change the products and mechanism of the photoconnersion of 4-CP in ice.
