FIELD: chemistry.
SUBSTANCE: method includes preparing an aqueous solution of a reducing agent in an aqueous solution of a stabiliser and introducing a reducing agent for metal salt to the solution. As a reducing agent, quercetin with a concentration of 1⋅10-3 up to 14⋅10-3 mole/liter is used in its deprotonated form at a molar ratio of quercetin with ammonia in the interval 1:3-1:10, while the oxidized form of quercetin acts as a stabiliser of nanoparticles. The concentration of the additional substance stabiliser varies from 1⋅10-3 up to 5 mol/liter, silver nitrate is used as metal salt. The concentration of silver nanoparticles in the resulting solution is from 500 ppm to 2500 ppm.
EFFECT: decreasing the consumption of the stabiliser, toxic and aggressive chemicals are not used.
