Abstract

L'invention concerne des solutions colloïdales de nanoparticules d'argent et un procédé pour leur préparation et peut être utilisée dans différents domaines, en particulier en médecine, science vétérinaire, industrie alimentaire, cosmétologie, chimie domestique et agrochimie. Le procédé comprend la dissolution électrochimique d'argent dans l'eau déminéralisée. L'argent sous forme de poudre fine ayant une pureté chimique de 99,999 % et avec des tailles de nanoparticule allant jusqu'à 100 nm est soumis à une dissolution électrochimique dans un dispositif d'électrolyse, dans lequel sont situées les électrodes sous forme de récipients constitués de matériau chimiquement neutre, dans lesquels de 100 à 150 g de poudre fine d'argent sont placés, et au moyen d'un conducteur recouvert par un revêtement chimiquement neutre une tension directe dans la plage de 30 à 45 volts est produite. L'électrolyse est réalisée dans des conditions de polarité de tension cyclique toutes les 2 heures et avec agitation mécanique de la solution 2 fois en vingt-quatre heures jusqu'à l'obtention d'une concentration d'argent dans la solution colloïdale de 5,0 à 100 mg/l. Lorsque la portion de nanoparticules de métal d'argent est de 5 à 90 % de la concentration totale d'argent en solution, la portion de nanoparticules dans la plage de 2 à 15 nm est de 65 à 85 % du volume total de nanoparticules de métal d'argent en solution, la portion de nanoparticules dans la plage de 15 à 35 nm est en correspondance de 15 à 35 %, la portion résiduelle de la concentration totale d'argent en solution est constituée d'ions d'argent. Le résultat technique de l'invention est la préparation de la solution colloïdale stable de nanoparticules d'argent.
