Abstract
The present research reports the synthesis of poly-N-isopropylacrylamide / mesoporous carbon composites, prepared by radical
polymerization of N-isopropylacrylamide inside mesoporous carbon pores functionalized with carboxylic groups. The deposition
of poly-N-isopropylacrylamide on mesoporous carbon was confirmed by FT-IR spectroscopy, TEM, N2-sorption measurements.
The mesoporous carbon material was found to adsorb vitamin B2 from aqueous solution at room temperature. The obtained
composite, poly-N-isopropylacrylamide / mesoporous carbon, exhibited a higher adsorption capacity for vitamin B2 as compared
to un-functionalized mesoporous carbon sample, due to hydrogen bonding between carbonyl groups of poly-Nisopropylacrylamide
immobilized on the mesoporous carbon surface and amino groups of vitamin B2 molecules.
