چکیده
|
1,3-dialkylimidazolium-based ionic liquids were chemically synthesized and bonded on the surface of magnetic nanoparticles (mnps) with easy one-step reaction. the obtained six kinds of ionic liquid modified mnps were characterized with transmission electron microscopy,thermogravimetric analysis,magnetization,and ftir,which owned the high adsorption capacity due to the nanometer size and high-density modification with ionic liquids. functionality of mnps with ionic liquids greatly influenced the solubility of the mnps with organic solvents depending on the alkyl chain length and the anions of the ionic liquids. moreover,the obtained mnps showed the specific extraction efficiency to organic pollutant,polycyclic aromatic hydrocarbons,while superparamagnetic property of the mnps facilitated the convenient separation of mnps from the bulks water samples. © 2013 ying li et al.
