“…2. The XPS spectrum showed two peaks at 642.2 and 653.9 eV correspond to Mn 2p3/2 and Mn 2p1/2, respectively, with a spin-energy separation of 11.7 eV, which was similar to 11.8eV reported by other researchers [10]. These results indicated that manganese oxide existed in the form of MnO 2 on the Mn@GAC catalyst.…”

Abstract. Adsorption performance of catalysts and catalytic ozonation of organic pollutants from bio-treated dyeing wastewater were investigated. Among various catalysts, the granular activated carbon (GAC) showed the better adsorption performance for removal of COD from dyeing wastewater, and the adsorption capacity was 2.1 mgCOD/gGAC. In addition, Mn@GAC composite catalyst was prepared by an impregnation method and used for catalytic ozonation.The XPS results showed that Mn was located onto GAC surface in the form of MnO 2 .The catalytic ozonation for COD removal efficiency was 41.7% with Mn@GAC. Therefore, the Mn@GAC catalytic ozonation is feasible for removal of the refractory organic pollutants from the dyeing wastewater.

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 0.75mg/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.

Sonuçlar çözünmüş organik karbon (ÇOK), UV254, SUVA254 (254 nm'de (spesifik Ultraviyole absorbansı) ve renk absorbansı (A436) parametreleri ölçülerek değerlendirilmiştir. 60 dakikada pH 6.5'da 10 mg/L ozon konsantrasyonunda yalnız başına ozonlama ile %21,4 ÇOK giderimi elde edilirken demir kaplı zeolitle (0,75 mg/L) katalitik ozonlama deneylerinde %62 ÇOK giderimi elde edilmiş, katalitik ozonlama sistemine 1 mg/L hidrojen peroksit ilavesiyle de (%64,6 ile ) çok hafif bir artış gözlenmiştir. katalitik ozonlama yalnız başına ozonlamaya kıyasla UV absorplayan aromatik yapının parçalanmasına katkıda bulunmuş ve ÇOK giderimini de iyileştirmiştir ancak katalitik ozonlama sistemlerinde ozon konsantrasyonunun artışı giderim veriminde kayda değer bir artış sağlamamıştır.
