Popis:	The absorption of ozone and reaction with a high molecular weight anthraquinone dye was studied in a tubular in situ ozone generator and reactor. In this reactor, ozone is generated around the periphery of the porous tubular reactor by corona discharge, and the generated ozone migrates through the pores and reacts with the contaminated fluid flowing in the tubular electrode. Dye oxidation was modeled to account for dye decolorization reaction with molecular ozone in the hydrodynamic film and bulk liquid. A parallel second order reaction stoichiometry was used to represent reaction of ozone with the dye to form primary and secondary products. The model developed represents physical phenomena well, as indicated by the good match between model predictions and experimental data. The reaction rate constants estimated from the model are invariant with initial dye concentration. Moreover, the model can predict the extent of reaction in the film and the bulk liquid based on input parameters.
