FIELD: colloidal chemistry; preparation of colloidal solutions containing colloidal particles with metal; preparation of cosmetic compounds, drugs, edible and biological additives, medical articles and materials.
SUBSTANCE: preparation of colloidal solutions of metals selected from group 2 and/or fourth period of Mendeleev's table in presence of organic compound containing heteroatom-oxygen or nitrogen is performed by electrochemical interaction at change in rate of dissolving of metal when polarity of electrodes is changed every 10 s; if necessary, process may be performed at constant drop of voltage from 1.8 to 0.2 V. Concentration of aqueous solution of organic compound is 0.1-100 mmole/l. Concentration of finished product (colloidal solution of metal) thus obtained ranges from 0.01 to 4 mmole/l and size of particles ranges from 0.1 to 90 mcm.
EFFECT: possibility of storage of metals without aggregation at room temperature for about three years.
