Enhanced transformation of aquatic organic compounds by long-lived photooxidants (LLPO) produced from dissolved organic matter
Urs von Gunten, Silvio Canonica, Stephanie Christa Remke
Dissolved organic matter (DOM) plays a crucial role in the photochemical transformation of organic contaminants in natural aquatic systems. The present study focuses on the characterization of a specific effect previously observed for electron-rich phenols ...
PERGAMON-ELSEVIER SCIENCE LTD2021Enhanced transformation of sulfonamide antibiotics by manganese(IV) oxide in the presence of model humic constituents
Urs von Gunten, Jin Jiang, Jun Ma, Yang Song, Yang Zhou
In this study, a manganese(IV) oxide-mediator (MnO2-mediator) system for the abatement of sulfonamide antibiotics was evaluated. Two simple model humic constituents, syringaldehyde (SA) and acetosyringone (AS), could promote the transformation of sulfonami ...
PERGAMON-ELSEVIER SCIENCE LTD2019Probing the Photosensitizing and Inhibitory Effects of Dissolved Organic Matter by Using N,N-dimethyl-4-cyanoaniline (DMABN)
Urs von Gunten, Frank Jonathan Leresche, Silvio Canonica
Dissolved organic matter (DOM) can act as a photosensitizer and an inhibitor in the phototransformation of several nitrogen-containing organic contaminants in surface waters. The present study was performed to select a probe molecule that is suitable to me ...
American Chemical Society2016Photosensitizing and Inhibitory Effects of Ozonated Dissolved Organic Matter on Triplet-Induced Contaminant Transformation
Urs von Gunten, Silvio Canonica
Dissolved organic matter (DOM) is both a promoter and an inhibitor of triplet-induced organic contaminant oxidation. This dual role was systematically investigated through photochemical experiments with three types of DOM of terrestrial and aquatic origins ...
