MODIFICATION OF ORGANIC LIGAND IN A Zr-MOF MATERIAL BY HYDROXYL GROUPS FOR ENHANCING ADSORPTION ABILITY OF Cu2+ ION IN AQUEOUS MEDIUM
Main Article Content
Abstract
In this study, HCMUE-2 material was successfully fabricated by combining the Zr4+ salt and hydroxyl-modified organic linker. Complete architectural characterizations of HCMUE-2 were confirmed through modern analysis procedures, including powder X-ray diffraction analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis measurement, and surface morphology analyses such as SEM and TEM incorporating with EDX spectrum. Accordingly, the maximum adsorption capacity of Cu2+ over HCMUE-2 is 1115.03 mg·g-1 at pH = 5.0, much higher than previously reported MOF materials. Notably, the obtained results of the Cu2+ removal are fitted with Langmuir isotherm and pseudo-second-order models, exhibiting that the Cu2+ adsorption onto HCMUE-2 is a chemical adsorption. Noteworthily, the structural robustness of HCMUE-2 is retained after adsorption, with the adsorption yield of Cu2+ (90%) without any considerable decrease after seven cycles. These findings indicate that HCMUE-2 is a potential material for eliminating the toxic Cu2+ ions from wastewater.
