Fabrication of Cerium Metal-Organic Frameworks Functionalized with Glutamic Acid for Adsorption of Basic Red 46 from Aqueous Solutions: Kinetics, Thermodynamics, and Optimization.

ABSTRACT: This research investigated the efficient removal of cationic Basic red 46 (BR46) dye from aqueous solutions, by means of cerium metal-organic frameworks (Ce-MOF) functionalized with glutamic acid to create NH₂-Ce-MOF. The NH₂-Ce-MOF was easily produced through a postsynthesis functionalization strategy and extensively analyzed through numerous methods with X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray (EDX), and N₂ adsorption/desorption isotherm. The findings revealed that the synthesized adsorbent had a high surface area of 1158.8 m²/g, a pore size of 1.511 nm, and a pore volume of 0.875 cm³/g. Upon adsorption of the BR46 dye, the surface area decreased to
