The use of industrially available inexpensive materials will ensure the cost-effectiveness and environmental attractiveness of the process. The proposed project is aimed at developing cost-effective methods for water purification from heavy metals and organic pollutants based on an integrated approach, which includes the adsorption of heavy metal ions by nanocomposite membranes and the oxidation of organic compounds using the Fenton system using heterogeneous catalysts. popup.description2 The object of the research is nanocomposite organo-inorganic and polymer adsorption membranes based on acrylic and vinyl monomers, as well as sol–gel systems based on alkoxysilanes. The subject of the research is the synthesis of polymer and nanocomposite organo-inorganic membranes of various compositions based on acrylic and vinyl monomers using the sol–gel method with adsorption properties; investigation of the structure and morphology of the obtained membranes; and study of the adsorption activity of polymer and nanocomposite organo-inorganic membranes. The aim of the work is to develop methods for the synthesis of new functional polymer and nanocomposite membranes with adsorption properties for the purification of natural and wastewater. The use of industrially available low-cost materials ensures the economic efficiency and environmental attractiveness of the process. Polymer membranes were synthesized by photo-initiated copolymerization of a mixture of acrylic monomers, including a monomer containing sulfonic acid groups, in predetermined molar ratios calculated on the basis of kinetic data using the Alfrey–Price equation. Nanocomposite organo-inorganic membranes with a homogeneous structure were synthesized by combining radical polymerization with the in situ sol–gel method in a system based on two alkoxysilanes; the homogeneous structure was confirmed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The synthesized membranes were investigated with respect to their mechanical and adsorption properties. High efficiency of the membranes as adsorbents for Co(II) and Ni(II) ions from natural and wastewater was established, with adsorption increasing as the pH of the solutions increased in the range of 2–6. A positive effect of the nanoporous structure of the organo-inorganic membranes on their adsorption capacity was demonstrated. Product Description popup.authors Mariia M.
