摘要：A colloidal dispersion having carrier particles of silica having a particle size from3 nm to 100 nm to which silver ions have been adsorbed, preferably in an amount of0.0005-5 silver ions per nm2 of silica particle surface. The surface of the carrier particles
of silica suitably contains aluminumsilicate sites. It also relates to a process for making acolloidal dispersion comprising providing a silica sol, adding a solution of silver nitrate tothe silica sol under agitation yielding a colloidal dispersion with silver ions adsorbed onthe surface of the silica particles. The dispersion is usable as a biocide in e.g. coatings,adhesives and sealants, in surface treatment and impregnation of organic materials, insurface treatment and impregnation of inorganic materials, in textiles, garments andshoes, in medical disposables, in plastics and rubbers, in water and air purification, and incrop protection.
