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

Caffeine oxidation by sono-Fenton treatment

Lomas J., (Corresponding) Villota N., Ferreiro C., Camarero L., Lombraña J.

Topic:

Advanced oxidation processes

Oxidation of waters containing caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720 W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe]=0-100.0 mg/L and oxidant concentrations between [H2O2]=0-250.0 mM. The oxidation of...Read more

Sonolytic and hybrid-sonolytic degradation of 6-hydroxy-methyl uracil, a model compound for the study of cyanotoxin cylindrospermopsin.

Voumvouraki M., Synefakis E., Christophoridis C., (Corresponding) Bizani E., Hiskia A., Thomaidis N.

Topic:

Advanced oxidation processes

The occurence of cyanotoxins, produced from cyanobacterial blooms, in the aquatic environment, has been a topic of great importance for scientists and authorities, over the last years. Cyanotoxins can greatly affect humans and fauna [1], therefore, their inclusion in monitoring programmes and in...Read more
