Nitrate-induced photooxidation of trace organic chemicals in water.
TLDR
The oxidation kinetics of butyl chloride, nitrobenzene, anisole, and methylmercury in the presence of hydroxyl radical (OH) scavengers were used to determine the rate and quantum efficiency for production of OH from irradiated nitrate ions in water.Abstract:
The oxidation kinetics of butyl chloride, nitrobenzene, anisole, and methylmercury in the presence of hydroxyl radical (OH) scavengers were used to determine the rate and quantum efficiency for production of OH from irradiated nitrate ions in water. The experiments were conducted under steady-state irradiations with monochromatic radiation (313 nm) and with sunlight. The mean quantum efficiency for OH production at 313 nm rises from 0.013 +/- 0.002 at 20 /sup 0/C to 0.017 +/- 0.003 at 30 /sup 0/C in the pH range 6.2-8.2. Results of this study are used to estimate nitrate-induced photooxidation rates of trace organic chemicals under a variety of environmental conditions. 27 references, 6 figures, 2 tables.read more

TL;DR: Aquatic and terrestrial plants and microorganisms were screened to test their ability to remove the herbicide, atrazine, from the environment as discussed by the authors, and the results indicated that microorganisms played only a minor role in the disappearance ofatrazine.

TL;DR: The ability of EPS to facilitate interactions between bacteria and sensitizers in photochemical disinfection processes is shown, and the presence of nitrate in photochemistry disinfection was not sensitive to EPS level.
