Synthesis and Characterization of Iron-Based Metal-Organic Framework as a Potential Adsorbent For The Removal Of Rhodamine B And Brilliant Green Dyes

Industrial dye wastes having low degradation become highly dangerous and carcinogenic to aquatic and human life, consequently being detrimental to the environment's biodiversity. The current research assessed the efficiency of iron metal organic framework (Fe-BDC MOF) for detoxifying the potentially lethal dyes Brilliant Green and Rhodamine B from aqueous media. Various characterization techniques were used to characterize the synthesized MOF. The adsorption capabilities and effectiveness of Fe-BDC MOF for the elimination of both the chosen dyes have been examined through numerous factors like pH, time in contact, dye concentration, temperature and sorbent dosage. The consequences revealed that, by increasing the temperature and sorbent amount, the efficiency of removing dyes was increased up to 99.035% for Brilliant Green and 98.5747% for Rhodamine B. The ongoing process of adsorption has been examined by the Langmuir and Freundlich isotherm models. The results revealed that the Langmuir adsorption isotherm was most suitable for the sorption method of both the selected dyes. The Laggergren’s and Ho’s kinetic models were used to determine different kinetics parameters. The Ho’s kinetic model is demonstrated to be the well-fitting model for the elimination of both dyes. Whereas thermodynamic studies confirmed that the sorption was spontaneous and endothermic.
