Magnetic Nanoparticles for PAHs Solid Phase Extraction

Chemical Engineering Transactions, 2016
In this paper a novel approach to the preparation of a solid-phase extraction sorbent, 1,4,7,10-tetrabenzyl- 1,4,7,10-tetraazacyclododecane (TBCD)/magnetic nanoparticles, was developed. The four benzyl groups of TBCD provide the TBCD functionalized Fe3O4 with strong adsorption capacity for polycyclic aromatic hydrocarbons (PAHs), due to their ...
