Abstract: Fe3O4 nanoparticles were covalently functionalized by N-(quinoline-8-yl)-2-(3-triethoxysilyl-propylamino)- acetamide (QTPA), and finally utilized to be magnetic chemosensor for sensitive and efficient Cu2+ removal in aqueous solution. Fourier FT-IR, TEM, XRD and XPS results showed that QTPA was bonded to the surface of Fe3O4 nanoparticles. At room temperature, the magnetic chemosensor exhibited high removal efficiency towards Cu2+.
