Journal ArticleDOI
Fate of pharmaceuticals--photodegradation by simulated solar UV-light.
TL;DR: The extent of photoinduced degradation of pharmaceuticals can vary significantly for the different pharmaceuticals and it strongly depends on the water constituents present in solution, and the irradiation experiments showed a pseudo-first-order kinetics.
Journal ArticleDOI
Kinetic study of photocatalytic degradation of carbamazepine, clofibric acid, iomeprol and iopromide assisted by different TiO2 materials--determination of intermediates and reaction pathways.
TL;DR: This study proves the high potential of the photocatalytic oxidation process to transform and mineralize environmentally relevant pharmaceuticals and contrast media in water.
Journal ArticleDOI
Removal of selected persistent organic pollutants by heterogeneous photocatalysis in water
TL;DR: In this paper, the active metabolite clofibric acid of some lipid lowering agents, the anti-epileptic drug carbamazepine and the X-ray contrast media iomeprol were selected.
Journal ArticleDOI
Photocatalytic degradation of carbamazepine, clofibric acid and iomeprol with P25 and Hombikat UV100 in the presence of natural organic matter (NOM) and other organic water constituents.
TL;DR: The results of this work prove that photocatalysis is a promising technology to reduce persistent substances like NOM, carbamazepine, clofibric acid, iomeprol and iopromide even if they are present in a complex matrix.

Fate of pharmaceuticals in rivers: deriving a benchmark dataset at favorable attenuation conditions
Uwe Kunkel,Michael Radke +1 more
TL;DR: To elucidate the ceiling of attenuation rates of pharmaceuticals in rivers, a study at a river with favorable conditions for the elimination of organic micropollutants was carried out at a small stream in Germany.

Paramagnetic Resonance Study of Liquids during Photolysis: Hydrogen Peroxide and Alcohols
Ralph Livingston,Henry Zeldes +1 more
TL;DR: In this article, the paramagnetic resonance spectra of free radicals in liquids have been studied during the course of intense irradiation with ultraviolet light, in which the liquid sample flows through the microwave cavity of the spectrometer and is photolyzed as it passes the sensitive region of the cavity.

Elektronenspinresonanz freier Radikale bei photochemischen Reaktionen von Ketonen in Lösung
H. Paul,Hanns Fischer +1 more
TL;DR: In this article, electron spin resonance was used to detect and identify alkyl and acyl radicals during UV-irradiation of dialkyl aryl ketones in liquid solutions and the results were discussed with respect to the photochemical behaviour of the ketones.
