Methylene Blue Adsorption Study Using Different Zno Types (Normal, Shaheed Factory, Nano)

The purpose of this research is to study the adsorption of methylene blue (M. B) on different types of ZnO ( normal, shaheed factory copper and brass industry& nano) at 298K& different M. B concentration, then choose which one is the best for the removal of M. B dye, the adsorption process studies an independent of temperature. The adsorption kinetic was achieved and oby the first order model. The adsorption isotherm for (normal& shaheed) ZnO was fitting to Freundlich model while nano ZnO was fitting to Temkin isotherm. Its clear that, nano ZnO is the best then normal ZnO and shaheed ZnO is the latest for the removal of M. B depend on % Removal and particle size. The three types of ZnO were identify by AFM (Atomic Force Microscope) to measure the particle size and scan its morphology.
