Bu
çalışmada hidrojen peroksit ve demir kaplı zeolitle katalitik ozonlama ile
humik asit giderimi incelenmiştir. 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.

Catalytic Ozonation for The Removal of Humic Acid in Water with Iron Coated Zeolite (ICZ)

Öz

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.
