Sažetak
In this study application of heterogeneous Fenton-type catalyst, Fe-exchanged zeolite, FeZSM5, for minimization of phenol and overall organic content in the model wastewater was investigated. Applied treatment systems included variation of heterogeneous and homogeneous Fenton type catalyst with and without the assistance of UV irradiation, FeZSM5/H2O2, Fe2+/H2O2/NH4ZSM5, Fe3+/H2O2/NH4ZSM5, UV/FeZSM5/H2O2, UV/Fe2+/H2O2/NH4ZSM5 and UV/ Fe3+/H2O2/NH4ZSM5. Processes’ efficiency was evaluated on the basis of the phenol removal, mineralization extent, H2O2 consumption and concentration of iron ions present in the wastewater after the treatment. By all applied systems complete phenol removal was achieved in less than 30 minutes of treatment time. Although systems including heterogeneous Fenton-type catalyst showed somewhat lower mineralization efficiency in comparison to the corresponding systems applying homogeneous Fenton-type catalysts and addition of synthetic zeolite, the fact that significantly lower concentration of iron ions is present in the wastewater after the treatment could afford these systems, particularly UV/FeZSM5/H2O2, great advantage toward the homogeneous Fenton type systems.
