| Özet |
| This study examined the catalytic ozonation of humic acid (HA) with iron coated zeolite (ICZ) and hydrogen peroxide (H2O2). The results were evaluated by DOC that specify organic matter, UV254, SUVA254 (Specific Ultraviole Absorbance at 254 nm), and A436. When ozonation was used alone, DOC removal was obtained as 21.4% at ozone concentration of 10 mg/L, pH 6.50 and oxidation time of 60 min. DOC removal was found to increase by the the addition of H2O2 in ozonation process. The use of ICZ as catalyst increased the decomposition of humic acid compared to ozonation alone. DOC removal efficiency was obtained as 62.0% at pH 6.5, at catalyst loading of 0.75 g/L, and oxidation time of 60 min. In catalytic ozonation process DOC removal slightly incresed, when H2O2 was added. 64.6% DOC removal was obtained at ozone concentration of 10 mg/L, catalyst dosage of 0.75 mg/L and H2O2 concentration of 1 mg/L. The catalytic ozonation enhanced the destruction of the aromatic and UV-absorbing structures compared with ozonation alone. However, increasing ozone concentrations did not increase removal efficiencies significantly in the catalytic ozonation processes. |
