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

Oxidation of acetaminophen by ultrasound waves and H2O2 combined technology

(Corresponding) Villota N., Lomas J., Ferreiro C., Camarero L., Lombraña J.
Topic: 
Advanced oxidation processes
This study analyses the colour acquired by oxidizing paracetamol aqueous samples through the combined US/H2O2 technology. When operating with only the action of the waves [US]=1.0 kWh/mmol C8H9NO2, the water acquires progressively hue according to a ratio of 0.0004 AU/min, with a degradation output...Read more
