The ozonation reaction of m-toluidine azodye is examined in a series of studies concerning the effect of ozone on oxidation and decolorization of wastewater from dye work. Chemical reaction rate constants are determined with respect to both ozone and dye to be 0.0225 and 0.0202 mg . min/sup -1/ . L/sup -1/, respectively. Using a proposed mathematical model to describe the overall reaction process, the mass transfer coefficient was found to be 0.19 min/sup -1/. Results are compared with those obtained in previous work for p-toluidine azodye at the same reaction conditions.
