Description

The photodegradation of pentachlorophenol (PCP) in hexane was investigated under xenon lamp irradiation. PCP was easily decomposed by 33.3min (500 counts) irradiation. The maximal degradation of PCP was observed at 292.1nm in the 100ppm solution and in a range of 252.6nm to 318.6nm in the 10ppm solution by 33.3min irradiation. At these wavelengths, PCP was completely degraded. Reductive dechlorination and replacement reaction of a chlorine atom with a hexyl group derived from the solvent used were observed. As the photodegradation products of PCP, 2, 3, 4, 5-tetrachlorophenol (TeCP), 2, 3, 4, 6-TeCP, 2, 3, 5, 6-TeCP, 2, 3, 4-trichlorophenol (TrCP), 2, 4, 5-TrCP, 3, 4, 5-TrCP, 2, 4-dichlorophenol (DCP), 3, 4-DCP, 3, 5-DCP and 3-chlorophenol were identified by gas chromatography-mass spectrometry. Besides the above compounds, three isomers of monohexyltetrachlorophenol and three isomers of monohexyltrichlorophenol were also tentatively identified.
