摘要：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,dichloroben-zaldehyde and pentachlorobiphenyls. The formation of photodegradation products indicate that the excited singlet oxygen and solvated electrons play a major contributors to the photodegradation process.
