Abstract
Sposób otrzymywania zawiesiny nanocząstek chitozan-srebro z roztworu chitozanu w kwasie octowym polega na tym, że roztwór chitozanu w kwasie octowym przy ciągłym mieszaniu dodaje się do wodnego roztworu tripolifosforanu sodu, po czym ustala się pH od 4 do 5 i ogrzewa się całość do temperatury od 20 do 80°C, po czym do tej zawiesiny przy ciągłym mieszaniu dodaje się wodny roztwór azotanu(V) srebra, a następnie wodny roztwór kwasu askorbinowego i utworzoną mieszaninę ogrzewa się do temperatury od 40 do 80°C. Przedmiotem wynalazku jest także nanokompozyt chitozan-srebro.The method of obtaining a suspension of chitosan-silver nanoparticles from a solution of chitosan in acetic acid is based on the fact that a solution of chitosan in acetic acid is added with continuous stirring to an aqueous solution of sodium tripolyphosphate, then the pH is adjusted from 4 to 5 and the whole is heated to a temperature from 20 to 80 ° C, then an aqueous silver nitrate (V) solution is added to this suspension with continuous stirring, followed by an aqueous ascorbic acid solution and the resulting mixture is heated to a temperature of 40 to 80 ° C. The subject of the invention is also a chitosan-silver nanocomposite.
