Application of Nanoparticles for Purification of Polluted Water

Abstract

For drinking water to be wholesome it should not present a risk of infection or contain unacceptable concentrations of hazardous chemicals to health as toxic metal ions and should be aesthetically acceptable to the consumer. The objective of this study was to synthesize mesoporous silica silver nanoparticles having strong antibacterial activity and high adsorption capacity to be applied in water purification as an effective alternative for traditional methods that are used in water purification. To achieve this target this study was designed to determine a method for the synthesis of small sized mesoporous silica silver nanoparticles, characterization of the synthesized nanoparticles, evaluation of the antibacterial activity of the obtained nanoparticles against Gram negative E. coli ATCC 5087, P.aeruginosa ATCC 9027 and S.typhi ATCC 700931 and Gram positive Methicillin-Resistant S.aureus ATCC 43300 (MRSA) as an important pathogens contaminating drinking water, assessment of the antibacterial activity of the synthesized nanoparticles at different temperatures and different pH values, evaluation of the antibacterial activity of the synthesized nanoparticles against a mixed culture of the tested bacteria (E. coli, P.aeruginosa, S.typhi and S.aureus), evaluation of the in vitro cytotoxicity of the synthesized nanoparticles, determination of the action of the
