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

Kinetics of the oxidation of model toxicants during photolysis of nitrites and nitrates in an aqueous medium
TL;DR: In this paper, the authors used the enzymic activity of luminescent bacteria and the reproductive function of Tetrahymena pyriformis infusoria as test functions to study the kinetics of the detoxication of model toxicants during photolysis of nitrite and nitrate.

Indirect photodegradation of ofloxacin in simulated seawater: Important roles of DOM and environmental factors
TL;DR: In this article , the role of dissolved organic matter (DOM) in the indirect photodegradation of ofloxacin (OFX) in simulated seawater was investigated, and it was shown that DOM can significantly accelerate the indirect photo-degradation of OFX.
