Herein, we have employed a convenient method to study kinetic and thermodynamic parameters of the adsorption of molybdenum from wastewater by using modified Zr‐based metal–organic frameworks, UIO‐66‐NH2‐X, as adsorbents. The frameworks were fabricated with a simple and fast method from terephthalic acids and Zirconium metal ions and modified via introduction of aldehyde groups using imine condensation. This is the first report in which MOFs have been utilized as adsorbents in molybdenum adsorption. The prepared adsorbents show high adsorption efficiency, which is representative of an improvement compared to other literature. The adsorption capacity and molybdenum removal for the modified framework are 667 mg/g and 93%, respectively which is a significant and remarkable value among other previously reported articles. The experimental adsorption data could be well interpreted with the pseudo‐second‐order kinetics and the Langmuir isotherm model. Thermodynamic studies illustrated a spontaneous exothermic mechanism for the adsorption process. [ABSTRACT FROM AUTHOR] |
