FIELD: chemical nano-structural preparations, liquid-phase compositions containing nano-particles of metals and having bactericidal, catalytic, corrosion-preventing and magnetic properties, possibly used in bio-technologies, medicine and nano-electronics.
SUBSTANCE: in order to receive micellar solution of stable metal-containing nano-structure particles, inverse-micellar dispersion is prepared on base of solution of surface-active matter in non-polar solvent, metal salt solution is added and then dispersion is agitated or it is subjected to ultrasound treatment for further deaeration of it. Metal ions are reduced by means of solvated electrons and radicals generated due to action of ionizing irradiation upon dispersion. Nano-structural particles are particles of metals, bimetals, sulfides or metal oxides. Metal salt is added in the form of aqueous, water-alcohol or water-ammonia solution. Sodium bis-2-ethylhexylsulfosuccinate is used, mainly as surface-active matter. Normal alkane, cyclic or aromatic hydrocarbons are used as organic solvent. Reduction by means of solvated electrons and radicals is realized in range of absorbed dozes 1 - 60 kGy by means of ionizing irradiation 60Co.
EFFECT: higher efficiency on uses the preparation.
