The study was undertaken to investigate the removal of reactive dyes: Orange 16 and Black 8, from aqueous solutions in the ozonation process. Experiments were carried under laboratory conditions at a concentration of both dyes reaching 100 mg dm⁻³ and at four doses of ozone – 16, 24, 32 and 40 g O₃ m⁻³. Reaction rate constants were determined for each experimental series. The research demonstrated that both the dose of ozone supplied and chemical structure of dye affected the rate of the dye removal process. An increase in ozone dose evoked an increase in the reaction rate constant for both dyes examined. The reaction rate constants determined at a stable dose of ozone for Black 8 were ca. 2 times higher than the constants calculated for Orange 16.
