| Abstract: | Mono-, di- and trichlorophenol including different isomers were degraded by O3, O3 + UV and O3 + UV + Fe3+. Disappearance rates are nearly identical among three ozonations. Whereas TOC elimination was not completed by ozone alone. UV illumination accelerated TOC elimination rate and the addition of Fe3+ (O3 + UV + Fe3+) further accelerated it. TOC elimination rates among different chlorophenols were in the order of mono > di > tri. The effect of Fe3+ was largest on the degradation of trichlorophenol. Hydroxylated aromatics, organic acids, formaldehyde and acetone were detected as intermediates. |
