Abstract: 

Magnetosensitive nanocomposites Fe3O4/SiO2, Fe3O4/TiO2, Fe3O4/Al2O3 based on single-domain magnetite are synthesized. The dependence of adsorption properties of nanocomposites on the chemical nature of their surface is revealed. The isotherms and the kinetics of adsorption of Zn2+, Cd2+, and Pb2+ cations and their mixtures from aqueous solutions are studied in a pH interval of 4.5–10.0. The nanocomposites had high biocompatibility, the extraction extent of the ions was 95–99%. The highest adsorption parameters for all the studied ions are demonstrated for Fe3O4/TiO2 nanostructures. The conclusion is drawn on prospects of the synthesized nanocomposites for the creation of adsorbents for medico-biological, technical, and ecological destinations.

Keywords: adsorption, biocompatible coatings, magnetite, magnetosensitive nanocomposites, metal cations, surface modification
