Abstract

Nanostructured AgI/TiO 2 was synthesized by deposition-precipitation method. The AgI/TiO 2 nanoparticles with different size were characterized using XRD and TEM methods. In order to compare the activity of these nanoparticles for removal of environmental pollutants, the adsorption of methyl violet by particles was studied. The equilibrium adsorption data were fitted to the different isotherms. The equilibrium data show that the modification of TiO 2 nanoparticles with AgI, leads to the higher adsorption capacity (more than twice) for methyl violet. The kinetic data for adsorption of methyl violet indicates that modification of TiO 2 with AgI leads to a stable adsorption.
