Three nanoparticles' materials are prepared, characterized and their performance was evaluatedfor efficient removal of five organochlorine, one organofluorine and six different kinds of bacteria. Gas chromatography/mass spectroscopy has been used to monitor the pesticides concentration before and after treatment by these prepared materials. Graphene gives the most efficient removal of these pesticides than graphene-silver composite but the later is more efficient for remediation of water contaminated with different kinds of bacteria.
