[Photodegradation of hexachlorobenzene in the presence of known organic constituents of atmospheric aerosols].
Hexachlorobenzene photolyzed completely in hexane solvent within several minutes under the radiation of a 500 W high pressure mercury lamp, while its photolysis rate in diisooctyl phthalate solvent, which was chosen as a model for the organic phase of atmospheric combustion aerosols, was over 70 times slower. Anthaquinone and methoxyl phenols that known as aerosol constitutes accelerated the photodegradations of hexachlorobenzene though possible energy transfer and hydrogen abstraction mechanisms, respectively. Pentachlorobenzene was the main photoproduct of hexachlorobenzene.
