Silica based on inorganic–polymer hybrid materials for removing toxic ions from wastewater

As a result of the adsorption of copolymer 5-(4-nitro)phenylazo-8-methacryloxyquinoline with methyl methacrylate on the surface of mesoporous silica gel, a new polymer-inorganic composite material was obtained. Based on the comparison of the sorption capacity of the synthesized composite and the composite based on silica gel with in situ immobilized poly-5-(4-nitro)phenylazo-8-methacryloxyquinoline, it was concluded that the method of in situ immobilization of complex-forming polymers on the surface of silica gel is more effective compared to their physical adsorption.
