FIELD: pharmaceuticals.
SUBSTANCE: invention relates to chemical-pharmaceutical industry and is a method for producing a concentrated solution of colloidal silver, consisting of electrochemical dissolution of silver at an initial voltage of 10–12 V, current density at the electrodes 45–62 A/m2 for a period of 4–8 to 80 hours with a cyclic reversal of the voltage polarity with a period of 15 minutes and stirring, characterized in that the electrochemical dissolution of silver is carried out in distilled water, in which as a stabilizer and for the creation of the initial electrical conductivity, a substance is introduced from the group of simple mono- or disaccharides in an amount providing a concentration of 1–3 g/l and silver for electrochemical dissolution is used in the form of plates of pure silver with a content of 99.9–99.99 %.
EFFECT: invention allows to simplify method of obtaining a concentrated solution of colloidal silver.
