Observations of 2,4,6-trichlorophenol degradation by ozone

摘要: The aqueous reactivity of 2,4,6-trichlorophenol (TCP) with ozone has been studied at laboratory-scale using a simple gas bubble/liquid contacting system. Degradation rate constants were measured directly and found to be 7.6 77.2 M(-1)s(-1) pH 2 7.5, respectively. At 10 min ozonation ( identical 15 mM consumption) achieved 90% degradation TCP, which corresponded the release approximately mol Cl(-) per TCP. presence hydrogen peroxide in solution did not significantly increase TCP but increased overall dechlorination 2.7 humic acid (HA) was enhance low relative HA concentrations (<0.6 g/g HA:TCP), reduce higher concentrations.
