SYNTHESIS AND CHARACTERIZATION OF IRON-BASED METAL ORGANIC FRAMEWORKS FOR REMOVAL OF METHYLENE BLUE

<strong>Abstract</strong>: The wastewater discharged from textile factories is the key present topic of water pollution problems. So, it is vital to reduce the pollutants from industrial effluents before their release into the environment. The current study was to investigate the appropriateness of iron dinitrobenzene carboxylic acid as effective adsorbents for removal of methylene blue from the textile wastewater. Batch adsorption experiments were optimized via adsorption parameters such as optimal adsorbent dosage, pH, initial MB concentration, and time were carried out to evaluate parameters that influence the adsorption process. The synthesized iron dinitro benzene dicarboxylic acid was analyzed by iodine number, and characterized by Fourier Transform Infrared and X-ray diffraction techniques. The result of the sample iron dinitro benzene dicarboxylic acid showed that the particle size is 0.97nm with amorphous structure. The performance of iron dinitro benzene dicarboxylic acid adsorbent is best at the optimum pH 6 with removal efficiency of 87.3. The optimum contact time was obtained at 90 minute for iron dinitro benzoic acid with removal efficiency 94.8%, while optimum adsorbent dosage was obtained at 0.5 gram with removal efficiency of 88.6%, and at the initial concentration of 1 ppm with removal efficiency of 93.5% iron dinitro benzoic acid adsorption experiment. The Adsorption isotherms results have well fitted to Freundlich isotherm than Langmuir isotherm. The adsorption kinetics results were best fitted the pseudo second order model. The result showed that iron dinitro had high removal efficiency. Application of this method can be economically and environmentally feasible to address wastewater problems. Further research has to be carried out on the removal capacity of this adsorbent for organic dyes not only from the textile industry but also from leather industries and soap industries. This is possibly due to the high porous nature and huge surface area of the as-synthesized sample.
