Development of Cu@Zr-MOFs-PAN Nanofiber Composites for Efficient Methylene Blue Adsorption in Wastewater Treatment.

ABSTRACT: Methylene blue (MB) is a commonly used dye that generates a large amount of dye wastewater during its application. If discharged untreated, it poses a serious threat to water environments and human health. Therefore, the removal of methylene blue from dye wastewater is crucial. In this study, we used zirconium-based metal-organic frameworks (Zr-MOFs) as a precursor and doped them with copper ions to prepare the Cu@Zr-MOFs composite material. Subsequently, we fabricated Cu@Zr-MOFs-PAN nanofiber composites through electrospinning to address the challenge of separating Cu@Zr-MOFs from water. The results indicate that the introduction of copper ions significantly enhances the adsorption capacity of Zr-MOFs for MB, increasing the adsorption amount from 158.0 mg/g to 266.0 mg/g, representing a 6
