摘要：
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.
