Abstract
The method of producing silver nanoparticles using red sand may include the steps of adding red sand to water, mixing the red sand in the water, removing a supernatant from the red sand in water mixture after the mixture has settled, adding sodium hydroxide to the supernatant to form an alkaline solution, adding silver nitrate (AgNO) to the solution, and isolating a precipitated reaction product including the silver nanoparticles. The silver nanoparticles produced according to this method have antibacterial activity, whether used alone or in combination with standard antibiotics.
