Novel Applications of Silver Nanocomposites in Water Purification.

      Аннотация: Utilization of metal nanoparticles such as silver (Ag+) either embedded in nanocomposite membrane or in the form of nanofilaments can effectively and economically filter the contaminated water. Recently, evaluation of nanocomposites efficiency against bacterial pathogens and heavy metal contaminants in water sources are proved its lethal effect on bacterial contaminants and led to avoid the most of hygienic problems associated with water pollution and overcome the resistance problem of pathogens to common disinfectants used in water purification. This book is discussed the mechanism of action of Nano-silver particles (Ag NPs), its antibacterial effectiveness, evaluation the disinfection efficiency of Ag NPs and the potential uses of novel Nano-silver composites involving polymeric membranes, chitosan/Nano-silver composite (Chitosan/Ag-NPs), rice husk-Nano-silver composite (rice husk/Ag-NPs). In addition to using of calcium hypochlorite-Nano-silver composite (Ca(OCl)2/Ag-NPs) as a bactericidal filter paper for water purification.
