Abstract：
:The disappearance and modeling of the ozonation of 2,4,6-trichlorophenol (TCP) was studied under different initial TCP concentrations and initial pH levels. The ozonation of TCP was found to follow a pseudo-first-order reaction. The degradation rates increased with the initial pH, and decreased with initial TCP concentration. 2,6-Dichlorohydroquinone was identified as the major intermediate, indicating that dechlorination and hydroxylation co-occurred during TCP ozonation. A model was proposed to quantitatively predict the pseudo-first-order rate constants under different initial TCP concentration and different initial pH levels. The proposed model can successfully describe the reaction; therefore another practical equation was proposed to predict the TCP removal rate at any detention time, which has high potential for practical applications and reactor design.
