Identification of TiO2/UV disinfection byproducts in drinking water

Article Abstract:

Only one byproduct is detected by a comprehensive analysis of titanium dioxide and ultraviolet light disinfection byproducts (DBPs) in drinking water. A single organic DBPs, temporarily identified as 3-methyl-2,4-hexanedione, was observed in ultrafiltered raw water treated only with TiO2/UV. However, a number of chlorinated and brominated DBPs were formed when chlorine was used as a secondary disinfectant, among them halomethanes and several halonitriles.

Ozonation byproducts of atrazine in synthetic and natural waters

Article Abstract:

The determination of the primary ozonation byproducts of atrazine in natural and synthetic waters is discussed. Experimental methods involve natural water characterization, analysis for s-Triazines and sampling. Degradation experiments were conducted on a completely mixed batch reactor. Although the primary ozonation byproducts of atrazine were determined, other compounds are still substantially existent.

Ozonation byproducts: identification of bromohydrins from the ozonation of natural waters with enhanced bromide levels

Article Abstract:

Bromohydrins are one type of chemical group byproduct of natural water ozonation in waters with large levels of bromide. Various methods were used to detect the bromohydrins, including gas chromatography, full-scan electron impact mass spectra and chemical ionization mass spectra. Gas chromatography used in conjunction with Fourier transform infrared spectra was especially efficient in detection.
