Adsorption properties of natural alumosilicate Ukrainian minerals, in situ modified by poly[8-methacroyloxyquinoline] to Pb(ІІ), Mn(ІІ), Cu(ІІ) and Fe(ІІІ) ions

Abstract

Immobilization of poly[8-methacroyloxy-quinoline] on a natural saponite surface immediately after polymer formation has been performed. The adsorption properties of the modified adsorbent with respect to Cu(II), Pb(II), Mn(II) and Fe(III) were studied. As a result of thermogravimetric analysis and DSC-MS analysis, it has been found that the composition of synthesized composite includes 10.14 wt% of polymer. As a result of the comparison of the sorption properties of the modified and original minerals with respect to the Pb (II), Cu (II), Mn (II) and Fe (III) ions, their improvement was recorded after modification by the polymer selected with respect to the ions Pb (II), Fe (III) and Cu (II).

Wood Polymer Composite Based on a Styrene and Triethoxy(Vinylphenethyl)silane

“…Recently, adsorption has been widely utilized to remove heavy metals from aqueous solutions due to its many advantages, such as low cost, easy handling, high removal efficiency, and environmental friendliness. [1][2][3] There are a lot of materials, including polymer-modified silica gel, [4][5][6][7] carbon nanocomposites, 8 magnetic nanoparticles (Fe 3 O 4 ), 9 fibers, 10 and modified natural clays 11,12 that have been used as adsorbents to remove heavy metals from aqueous solutions.…”
