In this study, bismuth ferrite) BFO ( particles were synthesized by sol-gel method. Bismuth ferrite, with high particle distribution and good response to Visible light was responsive. Azorubine was selected as a contaminant in this study. The pH value of a factor it is very effective in destroying the color of Azorubine. Structural, morphological and optical properties of BFO using X-ray diffraction (IR-FT), scanning electron microscopy (SEM-FE) and Visible-UV spectroscopy were analyzed. Effects of different parameters on degradation photocatalytic dye of Azorubine dye at a concentration of 10 ppm including H2O2 content, type of light emitted, pH value and dose. The nanoparticles used were investigated and optimized. Degree of Azorubine dye degradation using BFO nanoparticles during. The time of 120 minutes reached 93.93% to show that this research is an effective photocatalytic method for destroys the color of azorubine.
