Abstract
Zgłoszenie dotyczy sposobu wytwarzania zawiesiny nanocząstek srebra. Sposób wytwarzania zawiesiny nanocząstek srebra polega na redukcji soli srebra środkiem redukującym pochodzenia roślinnego i charakteryzuje się tym, że jako środek redukujący stosuje się hormon roślinny, przy czym redukcję prowadzi się w obecności stabilizatora. Według korzystnego wariantu wykonania sposób wytwarzania obejmuje następujące etapy: a) sporządza się roztwór stabilizatora w wodzie lub w mieszaninie rozpuszczalnika organicznego i wody, po czym w roztworze tym rozpuszcza się sól srebra (roztwór A); b) sporządza się roztwór hormonu roślinnego, korzystnie w tym samym rozpuszczalniku, w którym sporządza się roztwór A, przy czym stosunek wagowy bursztynu do rozpuszczalnika zawarty jest w granicach od 1 : 100 do 10 : 1 (roztwór B); c) roztwór B dodaje się do roztworu A, przy ciągłym mieszaniu, w temperaturze utrzymującej stan ciekły rozpuszczalnika lub podwyższonej do temperatury wrzenia rozpuszczalnika, przy czym stosunek objętościowy roztworu A do roztworu B zawarty jest w granicach od 1 : 100 do 100 : 1. Ujawniono także zawiesinę nanocząstek srebra, zawierającą hormon roślinny i stabilizator, w której stężenie nanocząstek srebra korzystnie zawarte jest w przedziale od 100 mg/dm3 do 5000 mg/dm3.The application relates to a method of producing a silver nanoparticle suspension. The method of producing a suspension of silver nanoparticles consists in reducing the silver salt with a reducing agent of plant origin and is characterized in that as a reducing agent plant hormone is used, the reduction being carried out in the presence of a stabilizer. According to a preferred embodiment, the production method comprises the following steps: a) a stabilizer solution is prepared in water or in a mixture of an organic solvent and water, after which the silver salt (solution A) is dissolved in the solution; b) a solution of the plant hormone is prepared, preferably in the same solvent in which solution A is prepared, the weight ratio of amber to solvent being in the range from 1: 100 to 10: 1 (solution B); c) solution B is added to solution A, with continuous stirring, at a temperature that maintains the liquid state of the solvent or is elevated to the boiling point of the solvent, the volume ratio of solution A to solution B being in the range from 1: 100 to 100: 1. Disclosed also a silver nanoparticle suspension containing plant hormone and stabilizer in which the concentration of silver nanoparticles is preferably in the range from 100 mg / dm3 to 5000 mg / dm3.
