“…The modification of natural polymers containing nanometer- and micron-sized metal particles in their composition is currently one of the intensively developing topical areas for the production of polymer materials [ 1 , 2 ]. The creation of such polymer materials is being actively developed at the junction of organometallic, coordination and chemistry of high-molecular compounds.…”

A magnetic polymer material based on natural polymers—humic acids and magnetite, pre-configured for the sorption of a metal ion—was obtained. The magnetic polymer material was obtained via the interaction of a natural polymer, magnetite nanoparticles and sorbed metal ions that were used as a template. Moreover, the formation of a pre-polymerization complex was followed by copolycondensation with an amine in the presence of a crosslinking agent and further removal of metal ions from the crosslinked copolymer. The physicochemical properties of the resulting materials were determined using various physical methods. The composition of the resulting magnetic polymer materials was characterized by elemental analysis using an Elementar Unicube elemental analyzer. It was found that the carbon content increases by 8.28% and nitrogen by 0.42% for the polymer material Fe3O4:HA:T:AA; for the polymer material Fe3O4:HA:AA, the carbon content increases by 14.61% and nitrogen by 3.01%. Based on the IR spectra data, it is clear that magnetic polymer materials have much in common before hydrolysis (Fe3O4:HA:T:AA) and after hydrolysis (Fe3O4:HA:AA). The structure of the resulting polymer materials was studied using electron microscopy. Micrographs show the presence of pores in magnetic polymer materials after acid hydrolysis, indicating the formation of imprints. The results of the study of the sorption properties of magnetic polymer materials showed that after acid hydrolysis, the sorption capacity of a customized magnetic polymer material increases two times and it can act as a magnetic sorption material.
