FENTON REAGENT IN COMBINATION WITH UV LIGHT AND ULTRASOUND WAVES APPLIED FOR CAFFEINE OXIDATION

Villota N., Lomas J., Lombraña J., Ferreiro C.

Topic:

Advanced oxidation processes

The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analyzed, operating at pH=3.0 and 25ºC using different AOPs, which combine the Fenton reagent ([H2O2]0=15.0 mM and [Fe2+]0=20.0 mg L-1) with low power UV light (15W,), medium (150W), and high (720 W). The Fenton reagent, combined...Read more

Investigation of variables affecting UV-LED photocatalytic degradation of antibiotics ciprofloxacin and sulfamethoxazole

(Corresponding) Bertagna Silva D., Buttiglieri G., Babić S.

Topic:

Advanced oxidation processes

In this study, photolytic and photocatalytic degradation of two antibiotics in ultra-pure water were analyzed. A lab-scale cylindrical reactor had its inner walls impregnated with TiO2 nanofilm for the photocatalytic experiments. In the first step, an optimized photoreactor design was chosen based...Read more
