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

Katalitik ozonlama proseslerinde nihai hedef kirleticinin son ürüne okside edilmesidir; fakat zincirleme oksidasyon reaksiyonları sonucunda bazı ara ürünler son ürüne kadar okside olamamaktadır. Bu oksidasyon ara ürünlerinin dezenfeksiyon işlemine tabi tutulması sonrasında ise daha toksik/kanserojenik/mutajenik ara ürünler meydana gelebilmektedir. Katalitik ozonlama prosesleri üzerine literatürde yapılan birçok çalışmada “hedef kirleticilerin” giderim verimliliği ve giderim maliyeti üzerine yoğunlaşılmış olsa da oluşan ara ürünler çoğu çalışmada takip edilmemiştir. Bu sebeple katalitik ozonlama proseslerinin nihai bertaraf yöntemi olarak kullanılabilirliği halen sorgulanmaktadır.

Removal of Natural Organic Matters from Aquatic Environment by Catalytic Ozonation Processes with Silver Nanoparticles: Determination of Ozonation Products

In catalytic ozonation processes, the ultimate aim is to oxidize the pollutant to the end product, but as a result of the chain oxidation reactions, some intermediates cannot be oxidized to the end product and after disinfection of the effluent waters, some toxic/carcinogenic/mutagenic intermediates may occur. Although many studies about catalytic ozonation processes, focused on the operating cost and the removal of target pollutants, the formation of intermediate products were not pursued. Therefore, the usage of catalytic ozonation processes as a final disposal method is still being questioned. Here, treatment of synthetically prepared humic acid solutions which represent natural organic materials in surface waters, by silver based nanoparticles enriched with montmorillonite 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. Trihalomethane (THM) and Haloacetic Acid (HAA) species formed by disinfection process with chlorine were analyzed quantitatively and other oxidation intermediates were determined qualitatively.
