Abstract
Sposób wytwarzania stabilnych suspensji nanocząstek srebra na drodze redukcji chemicznej jonów srebra, charakteryzuje się tym, że jako reduktor stosuje się fosfinian sodu w stężeniu molowym w mieszaninie reakcyjnej wynoszącym 5 do 50 mM, jako stabilizator stosuje się hektametafosforan sodu w stężeniu molowym w mieszaninie reakcyjnej wynoszącym 0,05 do 0,4 mM, a jako źródło jonów srebra stosuje się azotan srebra w stężeniu molowym w mieszaninie reakcyjnej wynoszącym 0,1 do 10 mM lub octan srebra w stężeniu molowym w mieszaninie reakcyjnej wynoszącym 0,1 do 20 mM. Roztwór fosforanowego reduktora łączy się z fosforanowym stabilizatorem i wprowadza roztwór soli srebra, a reakcję redukcji prowadzi się w temperaturze 40-60°C, zachowując pH mieszaniny reakcyjnej w przedziale 2,3 do 3,0. Zastosowanie stabilnych suspensji nanocząstek srebra uzyskanych sposobem określonym powyżej jako substancji do celów biobójczych, zwłaszcza bakteriobójczych, zgodnie z którym stężenie nanocząstek srebra w suspensji jest nie mniejsze niż 10,30 µg/ml.The method for producing stable suspensions of silver nanoparticles by chemical reduction of silver ions is characterized by the use of sodium phosphinate as a reducer at a molar concentration in the reaction mixture of 5 to 50 mM, and as a stabilizer sodium hexametaphosphate is used at a molar concentration in the reaction mixture of 0 .05 to 0.4 mM, and the source of silver ions is silver nitrate at a molar concentration in the reaction mixture of 0.1 to 10 mM or silver acetate at a molar concentration in the reaction mixture of 0.1 to 20 mM. The phosphate reducer solution is combined with the phosphate stabilizer and a silver salt solution is introduced, and the reduction reaction is carried out at a temperature of 40-60°C, maintaining the pH of the reaction mixture in the range of 2.3 to 3.0. The use of stable suspensions of silver nanoparticles obtained by the method specified above as substances for biocidal, especially bactericidal, purposes, according to which the concentration of silver nanoparticles in the suspension is not less than 10.30 µg/ml.
