Abstract
Commercial non-steroidal anti-inflammatory drugs (NSAIDs) are considered as toxic to the
environment since they induce side e ects when consumed by humans or aquatic life. Ibuprofen
is a member of the NSAID family and is widely used as an anti-inflammatory and painkiller agent.
Photolysis is a potentially important method of degradation for several emerging contaminants, and
individual compounds can undergo photolysis to various degrees, depending on their chemical
structure. The e ciency oftitanium dioxide (TiO2) and photocatalysis was investigated for the
removal of ibuprofen from the aquatic environment, and the performance of these di erent processes
was evaluated. In heterogeneous photocatalysis, two experiments were carried out using TiO2 as
(i) dispersed powder, and (ii) TiO2 immobilized on the active surface of commercial coated glass.
The kinetics of each photoreaction was determined, and the identification of the photoproducts was
carried out by liquid chromatography coupled with Fourier-transform ion cyclotron resonance mass
spectrometry (LC-FTICR MS). The overall results suggest that the TiO2 active thin layer immobilized
on the glass substrate can avoid recovery problems related to the use of TiO2 powder in heterogeneous
photocatalysis and may be a promising tool toward protecting the environment from emerging
contaminants such as ibuprofen and its derivatives.
