Magnetic bismuth ferrite nanoparticles were prepared by microwave method. We used Iron(III) nitrate nonahydrate, bismuth nitrate as initial reagents, glycine as an organic template and ammonium nitrate as co-oxidizer. This solid phase reaction was done under microwave radiation with the power of 900 W for 20 minutes. After the treatment, the result compound washed with distilled water and ethanol and dried at 70°C. This method has advantages such as simple, fast, reduces energy and environmental friendly. The product was characterized by Powder X-ray diffraction (PXRD), Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) and vibrating sample magnetometer (VSM). Also, the adsorption behavior of congo red as an organic pollutant was evaluated.
