Adsorption of Reactive Red 195 from polluted water by BiFeO3 particles |
|
| چکیده انگلیسی مقاله |
The origin of wastewater pollutants are different industrial activities such as textile, pulp manufacturing, Kraft bleaching industries, etc. The textile industries are the main source of this severe problem. Dyes in wastewater generate coloration and several environmental problems since they impede the reoxygenation capacity and the photosynthetic activity of organisms. adsorption has been used as the most effective method to treat this type of wastewater. In this paper used BiFeO3 as a non-toxicity perovskite that was synthesized by hydrothermal method to remove Reactive Red 195 from the aqueous solution. In terms of environmental remediation, BiFeO3 is being applied as a photocatalyst owning to its small band gap and has been studied intensively. However, to the best of our knowledge, little work has been focused on the adsorption performance of BiFeO3. The XRD pattern of BiFeO3 nanoparticles was prepared. The present study employed bismuth ferrite as a means to adsorb the commercially available red dye 195 in aqueous solutions. The findings revealed pronounced electrostatic interactions between the charged surface of the adsorbent and the anionic dye at acidic pH. The optimal dye absorption was observed at pH 4, resulting in complete absorption of the red dye 195 within 2 hours under dark conditions. |
