Özet
Degradation of an azo dye, Acid Red 73 (AR73), was examined in detail using the UV/H2O2/S2O8 2-/Fe2+ process. UV-Vis absorbance, total organic carbon, H2O2 concentration, and pH of solution were monitored during the mineralization process. The results indicated that the mineralization efficiency was optimized from 78.8 to 95.6 % as a result of increasing the initial concentration of S2O8 2- from 0.923 to 3.70 mM. The capability of this process was compared with those of UV/H2O2, UV/H2O2/Fe2+, and UV/H2O2/S2O8 2- processes. The UV/H2O2/S2O8 2-/Fe2+ process was more effective than other processes in degradation of AR73. Moreover, Fe2+ was immobilized on the surface of zeolite (ZSM5), and its immobilization effect was examined. Mineralization efficiency in the Fe2+ catalyzed process was higher than that of the Fe2+-ZSM5 catalyzed process.
