Title
Dissolved oxygen concentration: A key parameter in monitoring the photo-Fenton process
Abstract

Dissolved oxygen concentration variations have been investigated during the photo-Fenton process. Using Paracetamol as a model pollutant and dissolved organic carbon (DOC) removal as the priority objective, we have studied the effects of irradiance intensity (13–87 W/m2), iron concentration (0.09–0.45 mM), hydrogen peroxide concentration (9–45 mM) and finally DOC concentration (4–25 mM) on the relationship between the mineralization rate, the H2O2 reaction rate and the oxygen generation rate. A high level of oxygen generation is indicative of inefficient conditions whereas a decrease in dissolved oxygen concentration (i.e. generation rates near to zero) indicates a lack of hydrogen peroxide. As a consequence, dissolved oxygen monitoring has been presented as an easy, measurable tool for studying the evolution of the photo-Fenton process and its efficiency.
