Adriano S. Silva thanks his doctoral Grant with reference SFRH/BD/151346/2021 financed by the Portuguese Foundation for Science and Technology (FCT), with funds from NORTE2020, under MIT Portugal Program. This work was financially supported by UIDB/00690/2020 (CIMO), LA/P/0045/2020 (ALiCE), UIDB/50020/2020, UI-DP/50020/2020 (LSRE-LCM) and the project RTChip4Theranostics, with the reference NORTE-01-0145-FEDER-029394. Fernanda F. Roman acknowledges the national funding by FCT through the individual research grant SFRH/BD/143224/2019.
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.
