FIELD: chemistry.
SUBSTANCE: invention relates to colloidal chemistry and lignin chemistry, particularly to stabilizers of colloidal silver solution. Colloidal silver solution stabilizer is water-soluble products of hydrolytic lignin nitration, obtained by nitration of hydrolytic lignin for 2-30 minutes in a boiling water bath with mixtures of concentrated nitric acid and dimethylsulfoxide or water in ratio of 1:4 by volume, subsequent cooling and alkalization with 14 % ammonia solution and dilution with distilled water.
EFFECT: invention provides stabilizing properties during synthesis of colloidal silver formed during redox reaction of silver and glucose cations in aqueous ammonia solution.
