TI  - A disappearance model for the prediction of trichlorophenol ozonation.
PG  - 289-94
AB  - 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.
