Title
(EN) A WATER PURIFICATION COMPOSITION
(FR) COMPOSITION DE PURIFICATION D'EAU
Abstract
(EN) A water purification composition is disclosed. Said composition comprises porous granules of a particulate material, silver nanoparticles and polyvinyl alcohol matrix, wherein the silver nanoparticles and the particulate material are embedded in the polyvinyl alcohol matrix, the particulate material, polyvinyl alcohol and silver nanoparticles being present in a ratio of 100: 4.5: 0.7 to 100: 10: 0.7 on weight basis, and the porous granules having a size in a range of 0.1 mm to 3 mm. A method for preparing a water purification composition is also disclosed.
(FR) La présente invention concerne une composition de purification d'eau. Ladite composition comprend des granulés poreux d'un matériau particulaire, des nanoparticules d'argent et une matrice d'alcool polyvinylique, les nanoparticules d'argent et la matière particulaire étant incorporées dans la matrice d'alcool polyvinylique, le matériau particulaire, l'alcool polyvinylique et les nanoparticules d'argent étant présents en un rapport de 100 : 4,5 : 0,7 à 100 : 10 : 0,7 sur une base en poids, et les granulés poreux ayant une taille située dans une plage allant de 0,1 mm à 3 mm. L'invention concerne également un procédé de préparation d'une composition de purification d'eau.
