Ag or money has been used to benefit greatly because the silver has the characteristics of bacteria later, a number of silver apart to smaller nanometer level to increase the surface area in contact with raw and coated. chemically inert surface to prevent the silver nanoparticles together. This research focuses on the development, preparation of nano silver shell and applied in the environment. The factors that affect the particles coated silver nanoparticles on the surface of the nano-particles of silica spheres. The silica nanoparticles were prepared by Sol-gel using Ammonia as a catalyst. And improve surface 3-Aminopropyltrimetroxysilane Then coated with silver nano technology growing from seed metal using Sodium borohydride as a reducing agent and Polyvinyl alcohol is a substance stabilized. Silica nano particles are covered with tiny seeds Silver Nano. Silver nitrate reducing and then fill again with Formaldehyde solution will be gray and brown. To determine the chemical technique UV-Visible Spectroscopy and physical examination techniques Transmission Electron Microscopy showed that the spherical silica particles, the surface is covered with silver nano-particles uniformly and fairly complete. It was then tested to absorb heavy metals in waste water by studying the addition of a certain amount of heavy metals in the water. And check with the technical ability to absorb UV-Visible Spectroscopy.
