Abstract

This study presents the results of the synthesis, characterization, and adsorption capacity of organometallic framework materials based on Cu(II) and the organic ligand 1,3,5-benzene tricarboxylate (Cu- BTC). Cu-BTC was synthesized by simple microwave method, and FTIR, SEM, and XRD were measured to check the bonding, morphology, and crystal structure properties. Cu-BTC is an adsorbent to remove azo dyes such as methylene blue (MB) from water. Studies on the effects of pH, concentration, and adsorption time showed that MB was removed according to the Freundlich isotherm adsorption model and the apparent second-order kinetic model. Therefore, the multilayer MB adsorption mechanism on the Cu-BTC surface is heterogeneous and influenced by electrostatic attraction. These characteristics show that Cu-BTC is a promising material for removing MB from wastewater with potential applications in environmental treatment.
