Abstract : Crystal violet belongs to basic dye group. It is a mitotic toxin and a mutagen so there is concern regarding these chemicals making deleterious effect on biota and whole environment. Various methods have been developed for the treatment of dye effluents. Heterogeneous photocatalysis is one of the prominent ways for removing the dyes from effluent due to the ability of present method to fully mineralize the pollutant into CO2, H2O and mineral acids in the presence of metal oxide nano powder as catalysts. The photo catalysis is accelerated on addition of large band-gap metal oxides nano powder. In present study, BaO nanoparticles prepared using solution combustion method and used for the discoloration of crystal violet a basic dye. Synthesized nano powder was identified by using XRD, SEM, UV-Visible spectroscopy and EDAX. The average nanoparticle size was determined to be 36 nm. The experiments were conducted by adjusting factors such as catalyst dosage, pH, dye concentration and variable irradiation. The experimental results demonstrated that, the synthesized BaO nanoparticles showed a maximum degradation of 99.10%.

Keywords : BaO, Crystal Violet, Photocatalysis, Nanoparticles.
