In this experimental research the adsorption and photocatalytic properties of silica nanoparticles were used to disinfection water against the gram-negative Escherichia coli bacteria. Silica nanoparticles were synthesized by modified Stober method and characterized. TEM image shows that the prepared nanoparticles were spherical with 20-30 nanometers diameter and 4.25 eV bandgap energy. The disc diffusion test […]
