METHOD FOR OBTAINING NANOSTRUCTURE METAL PARTICLES Russian patent published in 2011 - IPC B22F9/24 C22B11/00 B82B1/00 

FIELD: metallurgy.

SUBSTANCE: method for obtaining nanostructure metal particles involves sorption of metal ions on cationite, desorption of metal ions with water and reduction of desorbed metal ions. At that, ion desorption is performed from cationite containing up to 35% of ions from total exchange capacity (TEC) of cationite. Desorption and reduction is performed by washing off the cationite with water to solution of the substance of the group of flavonoids. During sorption there used are ions of such meals as Ag, Cu, Ni, Fe, Cd. Desorption of metal ions is performed to solution of flavonoids with concentration in the range of 2·10^-5 - 30·10^-5 M to concentration of metal ions in the range of 2·10^-4 - 5·10^-3 M.

EFFECT: obtaining nanoparticles at total exchange capacity of cationites, enlarging the range of obtained nanoparticles of metals in "cationite-water solution of ions" system.
