FIELD: chemistry. ^ SUBSTANCE: invention can be used in coordination and colloidal chemistry. A mixture of organic substance and metallurgical dust containing 3d metals - iron or nickel undergoes mechanochemical processing and subsequently heated to (100-400)C without access to air. The organic substance used is polymer production wastes which contain carbon-chain polymers with side functional groups such as secondary polyvinylchloride or polyvinylacetate. If polyvinylchloride is used, hydrochloric acid is added to the initial mixture. To obtain nano-products in form of "rolls" with metal oxide nanocrystals inside, the mixture is subjected to stage heating at temperature not exceeding 300C, with subsequent alkali treatment of the product obtained in form of nanofilms with metal-containing nanoparticles on the surface. ^ EFFECT: invention enables to lower cost of the nano-product owing to use of production wastes and to also obtain nano-structures with magnetic susceptibility. ^ 3 cl, 17 dwg, 5 ex |
