Abstract
The conditions for obtaining stable metallic silver hydrosols in the presence of flax fiber extracts have been studied by the method of «green chemistry» and the possibility of using synthesized sols to provide cellulose-containing materials with antimicrobial activity or biosecurity has been proved. The process of synthesis of ultrafine silver particles in the presence of concomitant natural impurities of flax fibers isolated from them during alkaline high-temperature treatment was studied by spectrophotometry, photon correlation spectroscopy and visual observation. The effect of the extract composition on dynamics of the formation of stable silver nanoparticles was determined. IR spectroscopy and potentiometric titration methods proved that an increase in the alkalinity of a cooking solution led not only to an increase in the amount of impurities in the solution, but also to their destruction, and the complex of reducing substances formed in the solution could act as a silver ion reducing agent even at a low extraction temperature. It was proven that antimicrobial activity against test cultures of synthesized sols and cellulose tissue treated with them depended on the conditions of synthesis.
