Gümüş nanopartiküller eşliğinde katalitik ozonlama prosesleri ile sucul ortamdan doğal organik maddelerin giderimi: Ozonlama ürünlerinin belirlenmesi

Öz:
Bu çalışmada, yüzeysel sulardaki doğal organik maddeleri temsilen sentetik olarak hazırlanmış hümik asit(HA) çözeltilerinin gümüş bazlı nanopartiküllerle zenginleştirilmiş montmorillonit (AgNP@MMT]katalizörlüğünde ozonlama prosesleri ile arıtılabilirliği araştırılmıştır. Katalizör dozlarının değiştirildiğiarıtım çalışmalarında doğal organik maddenin (DOM) bozunumu ve alifatik-aromatik yapısındakideğişimleri izlenilmiştir. Katalizör miktarındaki artışa bağlı olarak ÇOK giderimindeki değişkenlik %67,80-76,61 arasında olmuştur. Ayrıca heterojen katalitik ozonlamada •OH radikallerinin varlığı organik radikalharcayıcı olarak bilinen tert bütil alkol (TBA) kullanılarak kanıtlanmıştır. Arıtma işlemi sonrasında çıkışsuları klorla dezenfeksiyon işlemine tabi tutulmuş ve oluşan Trihalometan (THM) ve Haloasetik Asit (HAA)türleri kantitatif olarak diğer oksidasyon ara ürünleri ise kalitatif olarak tespit edilmiştir. THM ve HAAoluşum potansiyelleri, katalizör dozu ve süre artışına bağlı olarak maksimum %79,50ve %80,40 oranındaazalmıştır. Katalitik ozonlama ile HA’nın bozunumu sonucunda oluşan küçük molekül ağırlığına sahip araürünler, ortamdaki •OH ile tekrar reaksiyona girmekte ve farklı ara ürün gruplarını oluşturmaktadır. Ortamdatespit edilen ara ürünlerin yapısı incelendiğinde genel olarak aldehit, keton ve asit gruplarının baskın olduğugörülmüştür. Analiz sonuçları oluşan en önemli aldehitler arasında Benzaldehit ve 2,4-dihidroksi-6- (2'-oksoheptil) benzaldehit’in olduğunu göstermiştir.

Removal of natural organic matters from aquatic environment by catalytic ozonation processes with silver nanoparticles: Determination of ozonation products

Öz:
In this study, the treatment of humic acid (HA) solutions that represent natural organic materials in surface waters and prepared synthetically by montmorillonite enriched with silver-based nanoparticles (AgNP@MMT) catalyzed ozonation processes was investigated. Degradation of natural organic matter and changes in aliphatic-aromatic structure were observed in treatment studies where catalyst doses were changed. The variability in the removal of DOC depending on the increase in the amount of catalyst was between 67.80-76.61%. In addition, the presence of OH radicals in heterogeneous catalytic ozonation, has been indicated using tert-butyl alcohol (TBA), known as organic radical scavengers. Trihalomethane (THM) and Haloacetic Acid (HAA) species formed by the disinfection process with chlorine were analyzed quantitatively and other oxidation intermediates were determined qualitatively. The formation potential of THM and HAA was decreased by a maximum of 79.50% and 80.40% depending on the catalyst dose and time increase. Small molecular weight intermediates resulting from the degradation of HA by catalytic ozonation react with •OH in the medium and form different intermediate product groups. When the structure of the intermediates detected in the environment was examined, it has seen that generally aldehyde, ketone and acid groups were dominant. Analysis results showed that the most important aldehydes were benzaldehyde and 2.4-dihydroxy-6-(2'-oxoheptyl)benzaldehyde .
