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

Performance of metal-free carbonaceous catalysts in the removal of paracetamol by catalytic wet peroxide oxidation

(Corresponding) Santos Silva A., Henrique A., Steldinger H., Diaz de Tuesta J., Gläsel J., Correia Silva J., Etzold B., Gomes H.

Topic:

Advanced oxidation processes

The performance of metal-free carbonaceous catalysts was evaluated in the removal of paracetamol, chosen as model pharmaceutical micropollutant, by catalytic wet peroxide oxidation (CWPO). The carbon materials were prepared from pentaerythritol tetraacrylate and divinylbenzene copolymer with bis(2-...Read more

Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol

(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.

Topic:

Advanced oxidation processes

Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more

Magnetic CoFe2O4@carbon yolk-shell nanoparticles as catalysts for the catalytic wet peroxide of paracetamol

Silva A., Costa Guari N., Diaz de Tuesta J., Eno Pottker W., Yassue Cordeiro P., (Corresponding) Gomes H.

Topic:

Advanced oxidation processes

This work focuses the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging pollutant paracetamol. A magnetic core composed of CoFe2O4 is developed by a sol-gel method. The core is subsequently coated with a formaldehyde-...Read more
