2,4,6-トリニトロフェノール含有廃液の湿式酸化処理(物質生命化学科)

Abstract

Wet oxidation treatment of colored 2,4,6-trinitrophenol waste water were studied. As oxidation treatment methods, high-test hypochlorite method, TiO_2 photocatalyst and combined electrolysis method, Fenton method and photo-Fenton method were applied. The waste water was decolorized with these oxidation methods. The nitrophenol waste water was understood for decoloration and the oxidation by all oxidation processing methods. As reaction products, NO_2^-, NO_3^- and aliphatic carboxylic acids were identified. The order of the oxidation potential of these methods is as followed; the photo-Fenton method > TiO_2 photocatalyst and combined electrolysis method > high-test hypochlorite method(pH3) > high-test hypochlorite method(pH12) > Fenton method.
