Effectiveness application of Chitosan/Alginic/Copper–organic framework beads on removal of carbaryl carbamate from wastewater

Abstract

In this study, we concentrated on creating copper-benzene dicarboxylate metal organic frameworks (Cu-BDC MOFs) utilizing scrap copper metal that was obtained from used copper electrical wires. For practical applications, powdered forms of MOFs are typically poorly processed; as a result, Cu-BDC/chitosan/alginic beads were created by cross-linking chitosan, alginic acid, and Cu-BDC MOF. The carbaryl pesticide adsorption from wastewater still challenge due to its low adsorption capacity. Therefore, Copper-BDC/chitosan/alginic beads were compared to chitosan/alginic beads, and the results showed that the latter had a more effective adsorption capacity (225.51 mg g−1) than the former (95.71 mg g−1). Through the use of X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDX), and Brunauer-Emmett-Teller (BET), the physical and chemical properties of chitosan/alginic and Cu-BDC/chitosan/alginic beads were examined. It's interesting to note that the Cu-BDC/chitosan/alginic beads' morphology is homogeneous and has sizable holes. The uniqueness of the produced materials lends itself to desirable characteristics for the targeted isolation of carbaryl from wastewater. As a result of the current work, MOFs materials for the selective removal of pesticides from wastewater will commercially available and easily process.
