Photosensitized Decomposition of Trichlorobenzenes(TCBs) in Humic Acid(HA) Solution

The photodegradation of TCBs in humic acid solutions at pH 7 was evaluated under laboratory sunlight simulated irradiation for 8 and 42 days. The irradiation to TCBs in solution in the presence of humic acid produced trichlorophenols, dichlorophenols in addition to the minor photodegraded products such as dichlorobutadiene, dichlorobenzaldehyde and pentachlorobiphenyls. The formation of photodegradation products indicate that the excited singlet oxygen and solvated electrons play a major contributors to the photodegradation process.
