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.
