Synthesis, Sorption Properties, and Evaluation of Silica Gel with Adsorbed Poly[8-Oxyquinoline Methacrylate] as a Sorbent for Cu(II), Cd(II), Pb(II) and Fe(III) Ions
In the present study, a novel functionalized silica composite was prepared by adsorption of poly[8- oxyquinoline methacrylate] on the surface of silica gel. Immobilization of poly[8- oxyquinoline methacrylate] on the silica gel surface was confirmed using IR spectroscopy and thermogravimetric analysis combined with mass spectrometry. Scanning electron microscopy revealed that the polymer almost completely covers the surface of the silica gel in the form of agglomerates of different geometric shapes.
