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
Characterisation of Radioactive Contaminated Waste: Alpha-Induced Air-Fluorescence Detection Under Daylight Conditions
(Corresponding) Gamage K., Crompton A.
Topic:
Hazardous waste management
Short travel of alpha particles in environments complicated the detection and characterisation of alpha-emitting contamination in mixed radiation fields in nuclear decommissioning sites. As a result, detection of alpha-induced radioluminescence became popular in nuclear decommissioning applications...Read more
