- Аннотация: The structure and adsorption properties of industrial adsorbents of the Macronet series from the class ofhypercrosslinked polystyrenes (MN-200DR, MN-270) and ionites based on them (MN-500, MN-100, MN-270s)were studied. The parameters of the porous structure of the adsorbents are calculated based on experimental dataon the adsorption of nitrogen, argon, and carbon dioxide. It has been established that these adsorbents have ahierarchical nanoporous structure. Nanopore fractions identified: 0.5, 0.8, 2.1 ± 0.2, 4.2 ± 0.2, 50–500 nm. Themost developed system of micropores <1 nm with a specific surface area of up to 680 m2 g 1 are found in MN-270 and MN-100. Sulfocationites are distinguished by a lower content of micropores <1 nm (200–400 m2 g 1).Structural studies of Macronet adsorbents were carried out using the methods of electron scanning microscopy,infrared spectroscopy and X-ray phase analysis. Studies of the adsorption of phenol and metal ions from aqueoussolutions on adsorbents Macronet were conducted. The most effective adsorbents for absorbing metal ions arethose containing ultramicropores of 0.5 nm in size. Hypercrosslinked adsorbents are promising for use in sorptiontechnologies for the complex purification of water from metal ions and toxic organic compounds.
