Abstract

Dye removal of colored wastewaters using nanophotocatalytic process was developed in recent
years as an effective system. In the present research the nanophotocatalysts were characterized
by XRD, SEM and FTIR analysis then compression of TiO2-Ag and ZnO-Ag on the decolorization
efficiency was evaluated. Finally, influence of the key operator parameters was studied to
optimize the treatment process.
