Abstract

L'invention divulgue un agent de traitement antibactérien qui est en mesure de libérer des ions d'argent à une concentration juste suffisante dans de l'eau pure, telle que l'eau potable ou l'eau de circulation, rendant ainsi l'eau antibactérienne, et qui est en mesure de conserver l'aptitude à la libération de l'argent pendant un long laps de temps ; et un procédé de traitement de l'eau utilisant l'agent de traitement antibactérien. L'invention divulgue spécifiquement un agent de traitement antibactérien pour un traitement de l'eau, caractérisé en ce qu'il est composé d'une composition de résine contenant une résine présentant une teneur standard en eau de 1-10% en poids et 1-30% en poids d'un phosphate de zirconium substitué par de l'argent, qui est représenté par la formule (1), comme agent antibactérien. AgaMbZrcHfd(PO4)3∙nH2O (1) Dans la formule (1), M représente au moins un type d'ion choisi dans le groupe constitué par un ion de métal alcalin, un ion de métal alcalino-terreux, un ion d'ammonium, un ion d'hydrogène ou un ion d'oxonium ; a, b et c représentent, chacun indépendamment, un nombre positif ; d vaut 0 ou un nombre positif ; et n vaut 0 ou un nombre positif de 2 ou moins.
