Abstract
Przedmiotem zgłoszenia jest sposób uzyskiwania stabilnych suspensji nanocząstek srebra o dodatnim ładunku powierzchniowym na drodze redukcji chemicznej, z użyciem nieorganicznego czynnika redukującego, rozpuszczalnych w wodzie soli srebra jako źródła jonów srebra, a zwłaszcza azotanu(V) srebra lub octanu srebra oraz 2-aminotioetanolu jako stabilizatora. Sposób ten charakteryzuje się tym, że jony srebra, wprowadzone do wodnego środowiska reakcji w postaci azotanu(V) srebra lub octanu srebra, kompleksuje się 2-aminotioetanolem, wprowadzonym do środowiska reakcji w postaci chlorowodorku, po czym dokonuje się redukcji chemicznej skompleksowanych jonów srebra, stosując jako reduktor fosfinian(I) sodu w stężeniu molowym od 0,5 mM do 40 mM, przy czym roztwór reduktora wprowadza się do zakwaszonego roztworu kompleksów jonów srebra z 2-aminotioetanolem, zachowując pH mieszaniny reakcyjnej w przedziale od 2 do 4.The subject of the application is a method for obtaining stable suspensions of silver nanoparticles with a positive surface charge by chemical reduction, using an inorganic reducing agent, water-soluble silver salts as a source of silver ions, in particular silver nitrate (V) or silver acetate and 2-aminothioethanol as a stabilizer . This method is characterized by the fact that silver ions, introduced into the aqueous reaction environment in the form of silver nitrate or silver acetate, are complexed with 2-aminothioethanol, introduced into the reaction environment in the form of the hydrochloride, followed by chemical reduction of the complexed silver ions, using sodium phosphinate (I) as a reducing agent in a molar concentration from 0.5 mM to 40 mM, the reducing agent solution being introduced into the acidified solution of silver ion complexes with 2-aminothioethanol, maintaining the pH of the reaction mixture in the range from 2 to 4.
