resumo
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.
