Changes of dissolved oxygen during the caffeine oxidation by photo-Fenton

Villota N., (Corresponding) Lomas J., (Corresponding) Irene C.

Topic:

Advanced oxidation processes

The aim of this work is to analyse the changes of dissolved oxygen ([DO], mg/L) during the oxidation of caffeine waters by photo-Fenton treatment. The concentration of dosed hydrogen peroxide would be the addition of the stoichiometric [H2O2], which reacts with organic matter ([H2O2]esteq=2.0 mM),...Read more

Colour changes during the carbamazepine oxidation by photo-Fenton

Villota N., (Corresponding) Qullatein H., (Corresponding) Lomas J.

Topic:

Advanced oxidation processes

Oxidation of waters containing 50.0 mg L-1 of carbamazepine was conducted by a photo-Fenton reagent employing a UV lamp of 150W, at pH=3.0 and T=40°C. The oxidising action of hydrogen peroxide was studied in a range between [H2O2]0=0-15.0 mM. When applying stoichiometric ratios of 2 mol C15H12N2O:...Read more

A practical time discretization methodology for adjusting the dosage profile in photo-Fenton processes

Xiangwei Y., Graells M., (Corresponding) Perez-Moya M.

Topic:

Advanced oxidation processes

Photo-Fenton processes are effective for mineralizaing aqueous solutions containing emergent pollutants. Accordingly, a number of works has been dedicated to determining conditions enhancing their performance (Pouran et al.,2015; Wang et al.,2016). Despite improvements, solutions are still far...Read more

3D printed lab-scale raceway ponds reactors for photo-Fenton processes

Nasr Esfahani K., Zandi M., Travieso-Rodriguez J., Graells M., (Corresponding) Perez-Moya M.

Topic:

Advanced oxidation processes

Abstract Raceway pond reactors (RPRs) have been widely used in microalgae mass culture (Acien et al., 2013) and their application for micro pollutant removal in photo-Fenton processes has been recently assessed (Rivas et al., 2015). The main advantages of raceway pond reactors are being low cost...Read more
