Optical properties and photochemical production of hydroxyl radical and singlet oxygen after ozonation of dissolved organic matter

Frank Jonathan Leresche, Urs von Gunten

This study focuses on the effects of ozonation on the optical and photochemical properties of dissolved organic matter (DOM). Upon ozonation, a decrease in light absorption properties of DOM was observed concomitantly with a large increase in singlet oxyge ...

Laser flash photolysis study of the photoinduced oxidation of 4-(dimethylamino)benzonitrile (DMABN)

Silvio Canonica, Frank Jonathan Leresche, Urs von Gunten

Aromatic amines are aquatic contaminants for which phototransformation in surface waters can be induced by excited triplet states of dissolved organic matter ((DOM)-D-3*). The first reaction step is assumed to consist of a one-electron oxidation process of ...

Effects of Ozone on the Photochemical and Photophysical Properties of Dissolved Organic Matter

Silvio Canonica, Frank Jonathan Leresche, Urs von Gunten

This study focused on the effects of ozonation on the photochemical and photophysical properties of dissolved organic matter (DOM). Upon ozonation, a decrease in DOM absorbance was observed in parallel with an increase in singlet oxygen (O-1(2)) and fluore ...
