dc.description.abstract Nanoiron-containing adsorbents have been widely used for cleaning of waters contaminated with organic and inorganic pollutants. Nanoiron can be spread over an organic and inorganic liner. Using renewable bioresources (timber, agricultural wastes, waste of biotechnological processes, etc.) to obtain sorbents containing nanoiron and iron oxide is quite promising. Iron-containing sorbents were obtained using Alnus incana wood. To avoid the emission of organic components from the wood into water, their partial pyrolysis was carried out with the formation of 1-3 mm coal layer. 13-17% of iron was impregnated in pyrolyzed and non-pyrolyzed samples. Impregnation was performed by 0.2 M FeCL36H2O and 0.2 M Fe(NO)39H2O solutions. Reduction of impregnated in the wood Fe+3 ions to nanoiron was carried out by NaBH4 in an inert atmosphere. By this method, polyfunctional sorbents like Fe/wood and Fe0/C/wood were obtained. Fe3O4/C/Wood type sorbents were obtained by pyrolysis of Fe(NO3)3-wood complexes. The nanoiron was spread on wood linen by passing steam of iron (0) pentacarbonyl at 150–200°. Wood-Fe(CO)5 system fibers composed from spatial grains are formed in an autoclave during heating. Magnetite partially impregnated into 74the wood. The obtained sorbents easily cause degradation of halogenated organic pollutants (1,4-dichlorbenzol and 4-bromanaline) and completely remove Cu+2 ion from model solutions. en_US
