Abstract

Magnetic composite sorbents based on microporous and biporous hypercrosslinked polystyrenes (HCPs) with inclusions of iron oxide nanoparticles were studied by X-ray diffraction and differential thermal analysis. In microporous composites, the size of impregnated magnetite nanoparticles was less than ∼6 nm, the nanocomposites remaining optically transparent. Biporous HCPs (with micro- and macropores) had larger nanoparticles (∼16 nm). The sorption studies revealed that composite magnetic sorbents, as well as the starting hypercrosslinked polystyrenes, are effective adsorbents with high capacity for many compounds including toxic and physiologically active compounds.
