Electron-rich phenols for probing the photochemical reactivity of freshwaters

Article Abstract:

Researchers at the Swiss Federal Institute for Environmental Science and Technology, Dubendorf, Switzerland, examined the kinetics of depletion of electron-rich phenols in Swiss freshwater samples. Photooxidants are found to transform the electron-rich phenols.

Transformation kinetics of phenols in water: photosensitization by dissolved natural organic material and aromatic ketones

Article Abstract:

The photochemical reactivity of phenols to different types of dissolved natural organic material (DNOM) and aromatic ketones was investigated to elucidate the transformation kinetics of phenols in water. The results indicated that excited triplet states of DNOM acted as photooxidants for different methyl and methoxy phenols in sunlit waters. Other DNOM-derived photooxidants with relatively long lifetimes influenced phenol transformation rates.
