TİTANYUM DİOKSİT(TiO2) NANOPARTİKÜL MADDELERİN EVSEL ATIKSULAR ÜZERİNE UYGULANMASI: KİRLETİCİLERİN GİDERİMİ
Abstract
Titanyum, yerkabuğunda en bol bulunan dokuzuncu elementtir ve genellikle rutil, ilmenit ve sfen gibi minerallerde bulunur. Su ve atık su arıtımında adsorpsiyon, fotokataliz ve ileri oksidasyon prosesleri kullanılmaktadır. Bu prosesler arasında fotokataliz, kirletici içeriği yüksek atık suların arıtılması için güvenli, verimli ve çevre dostu bir arıtma prosesi olarak ortaya çıkmıştır. Titanyum dioksit (TiO2) fotokatalizör ve adsorban olarak yaygın kullanılmaktadır. Titanyum dioksit nanoparçacık malzemesi, çevresel su ve atık su arıtımı dahil olmak üzere çeşitli alanlarda uygulanmıştır. Bu çalışmada, evsel atıksularda kirleticilerin giderilmesi için TiO2 nanopartikülleri kullanılarak arıtma performansı araştırılmıştır. Sistem performansı, kimyasal oksijen ihtiyacı (KOİ), çözünmüş organik karbon (DOC) ve toplam nitrojen (TN) açısından değerlendirilmiştir. Optimum koşulları belirlemek için pH 7.2'de farklı adsorban konsantrasyonları (50-200 mg/L) ve reaksiyon süreleri (15-90 dakika) araştırılmıştır. Optimum adsorpsiyon konsantrasyonu ve reaksiyon süresi sırasıyla 50 mg TiO2/L ve 60 dakika olarak belirlenmiştir. KOİ, DOC ve TN giderim verimleri sırasıyla %80, %30 ve %35 olarak gözlenmiştir. Elde edilen sonuçlar, TiO2 nanoparçacıklarının evsel atık sularından KOİ ve DOC giderim verimi açısından yüksek olduğunu göstermektedir.

APPLICATION OF TITANIUM DIOXIDE(TiO2) NANOPARTICLE MATERIALS ON DOMESTIC WASTEWATER: REMOVAL OF POLLUTANTS
Abstract
Titanium is the ninth most abundant element in the earth's crust and is usually found in minerals such as rutile, ilmenite, and sphene. Adsorption, photocatalysis, and advanced oxidation processes are used in water and wastewater treatment. Among these processes, photocatalysis has emerged as a safe, efficient, and environmentally friendly treatment process for the treatment of wastewater with high pollutant content. Titanium dioxide (TiO2) is widely used as a photocatalyst and adsorbent. Titanium dioxide nanoparticle material has been applied in various fields, including environmental water and wastewater treatment. In this study, treatment performance was investigated by using TiO2 nanoparticles for the removal of pollutants in domestic wastewater. System performance was evaluated in terms of chemical oxygen demand (COD), dissolved organic carbon (DOC), and total nitrogen (TN). Different adsorbent concentrations (50-200 mg/L) and reaction times (15-90 min) were investigated at pH 7.2 to determine optimum conditions. Optimum adsorption concentration and reaction time were found to be 50 mg TiO2/L and 60 minutes, respectively. COD, DOC, and TN removal efficiencies were observed as 80%, 30%, and 35%, respectively. The obtained results showed that the removal efficiency of COD and DOC from domestic wastewater of TiO2 nanoparticles is high.
