Descrição
In this study, carbon-based magnetic nanoparticles (MNPs) have been prepared by sucessive sol-gel method for core bare preparation and carbon coated through polymerization of phloroglucinol/glyoxylic acid, which are greener carbon precursors than the conventional method of resorcinol/formaldehyde (R/F), since formaldehyde is known to be a carcinogenic reagent. The bare core (CoFe2O4) and the carbon-coated MNPs (CoFe2O4@C) were tested as catalysts in the removal of paracetamol (PCM) from an aqueous solution by catalytic wet peroxide oxidation under optimum operational conditions, pH 3.5 and 80 °C. Values of paracetamol abatment between 33.0 and 100% were achieved after 6 h of reaction for the bare core and the carbon-based MNPs, respectively.
