METHOD OF PRODUCING METAL NANOPARTICLES IN AQUEOUS MEDIUM Russian patent published in 2011 - IPC C25C5/02 B82B3/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to production of copper nanoparticles to be used as biocide component in medicine and veterinary science, etc. Proposed method comprises dissolving stabilising components in solvent, introducing anode nanoparticles, in the form of copper plate and node, into stabiliser solution, and electrochemical dissolution of anode in causing stabilised direct current to flow through the solution. Note here that distilled water is used as a solvent, while organic and inorganic stabilising components are used as stabilisers. Dissolution of stabilising components is carried out in two stages. Note here that, first, in heating and mixing, organic stabilising components are dissolved, and, then after cooling at mixing, inorganic components are dissolved. Note also that stainless steel plate is used as cathode.

EFFECT: production of nanoparticles with strongly pronounced bactericidal Catalytic, antirust and magnetic properties.
