tFerrite bismuth nanoparticles as a visible light photocatalyst were successfully synthesized via ultra-sound. The optimum conditions were found and applied for the sono-synthesis of the catalyst. The productwas characterized by different methods. The nanoparticles were used for the degradation of methyleneblue as a typical dye pollutant. In acidic medium, the photocatalytic degradation was carried out underdirect sunlight irradiation. In basic medium, without catalyst, the methylene blue was degraded throughphotolysis under sunlight irradiation. The effect of parameters such as the amount of catalyst and initialconcentration of the dye was investigated on the removal efficiency of methylene blue. The adsorptionisotherm and the kinetic of photocatalytic degradation were studied under different conditions. Further-more, the degradation efficiency and the chemical oxygen demand reduction were 100% and 83% for thephotocatalytic process, respectively.
