this paper summarizes the result of a degradation test of two azo-reactive dyes (reactive blue 214, reactive red 243) under uv irradiation in the presence of h2o2. five different doses of hydrogen peroxide (0 mm, 5 mm, 10 mm, 20 mm and 30 mm) at constant initial concentration of the substrate (100 mg/l) were used. the radiation source were three 15 w-lamps. complete destruction of the color of the solutions was attained in 40-50 min of irradiation. uv/h2o2 proved capable of complete discoloration and degradation of the above azo reactive dyes.
