US/H2O2 combined technology applied to the paracetamol oxidation

Villota N., (Corresponding) Jose L.
Topic: 
Advanced oxidation processes
This study analyzes 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

Effect of iron catalyst on caffeine oxidation by sono-Fenton technology

Villota N., (Corresponding) Lomas J., (Corresponding) Sardón L., (Corresponding) Ferreiro C.
Topic: 
Advanced oxidation processes
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe2+]0=0-100.0 mg L-1, using oxidant ratios of [H2O2]0=250.0 mM. The oxidation...Read more

Effect of hydrogen peroxide on caffeine oxidation by sono-Fenton technology

Villota N., (Corresponding) Lomas J., (Corresponding) Camarero L., (Corresponding) Ferreiro C., (Corresponding) Sardon L.
Topic: 
Advanced oxidation processes
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The oxidizing action of hydrogen peroxide was studied in a range between [H2O2]0=0-250.0 mM, using iron ratios of 0.7 mol Fe2+/mol C8H10N4O2...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
