FIELD: chemistry.
SUBSTANCE: invention refers to a nanocomposite solid material of hexa- and octacyanometallates, methods for preparing them and using as mineral fixing agents. What is presented is the nanocomposite solid material containing metal-coordination polymer nanoparticles with ligands CN, containing cations Mn+, wherein M is a transient metal, and n is equal to 2 or 3; and anions [M'(CN)m]x-, wherein M' is a transient metal, x is equal to 3 or 4, m is equal to 6 or 8; the above cations Mn+ of the coordination polymer are bound through the metal-organic binding to the organic group of organic grafting chemically attached inside pores of a porous glass carrier, and the pores of the porous glass are produced by the selective chemical etching of a borate phase of solid borosilicate glass.
EFFECT: presented material has a reproducible and controlled composition and properties that is ensured by the reliability of the method for producing, and has the excellent binding properties.
