Abstract
New magnetic adsorbents have been developed on the basis of lignocellulose fibers. The properties of original materials were supplemented with magnetic ones by a Layer-by-Layer (LbL) assembly of magnetite nanoparticles from a water-based magnetic fluid stabilized by tetramethylammonium hydroxide and polyelectrolytes (poly(diallyldimethylammonium chloride) or polyethylenimine). Sorption capacity of designed materials on heavy metal ions has been evaluated. Tables 2, Figs 4, Refs 11.
