  • Abstract

    This paper presents the achievability of removal of basic dye methylene blue (MB) from aqueous solutions by using homogeneous ZnO nanoparticles prepared by a very feasible modified chemical route. The prepared nanomaterial was characterized by Thermogravimetry, X-ray diffraction, Photoluminiscence, FT-Infra Red and UV-Vis Spectroscopy, and Transmission Electron Microscopy analyses. The morphology of the nanoparticles were found to be very homogeneous with particle size of around 20 nm. The dye degradation was monitored with UV-Vis Spectrophotometer and the photodegradation phenomenon followed pseudo first order kinetics.
