Use
Biological. In activated sludge, Photolytic. UV irradiation (λ = 2537 ?) of pentachlorobenzene in a hexane solution for 3 hours produced a 50% yield of 1,2,4,5-tetrachlorobenzene and a 13% yield of 1,2,3,5- tetrachlorobenzene (Crosby and Hamadmad, 1971). Irradiation (λ ≥285 nm)A carbon dioxide yield of 2.0% was achieved when pentachlorobenzene adsorbed on silica gel was irradiated with light (λ >290 nm) for 17 hours (Freitag et al., 1985).The experimental first-order decay rate for pentachlorobenzene in an aqueous solution containing a nonionic surfactant micelle (Brij 58, a polyoxyethylene cetyl ether) and illuminated by a photoreactor equipped with 253.7-nm monochromatic UV lamps, is 1.47 × 10–2/sec. The corresponding half-life is 47 seconds. Photoproducts reported include, alltetra-, tri- and dichlorobenzenes, chlorobenzene, benzene, phenol, hydrogen and chloride ions (Chu and Jafvert, 1994)
