Abstract

Selon un procédé permettant de préparer des solutions de stérilisation, on ajoute une poudre de cuivre fine à une solution aqueuse ayant un pH régulé par un acide organique, on agite le mélange obtenu avec un agitateur, on filtre le mélange de façon à obtenir un solution mère contenant des ions cuivre purs élués à partir du cuivre métallique, puis on dilue de manière appropriée la solution mère de façon à obtenir des solutions de stérilisation dont le composant principal est la solution aqueuse de l'acide organique contenant les ions cuivre purs. Ces solutions sont sans danger pour l'homme et ont d'excellents effets bactéricides à long terme. Elles peuvent donc être utilisées comme substituts des antiseptiques chlorés et alcooliques classiques et servir à la stérilisation des planches à découper dans les cuisines, des instruments dans les installations de traitement des aliments, de la vaisselle, des écoles, etc. Etant sans danger pour l'homme, ce sont les antiseptiques les mieux adaptés aux enfants et aux malades hospitalisés.
