Electrospun metal-organic frameworks hybrid nanofiber membrane for efficient removal of As(III) and As(V) from water

Metal-organic frameworks (MOFs) have been widely applied for pollutants removal in water. However, the powdered MOFs are always suffered from aggregation during use and difficult collection after use. These problems discount their efficiency and inhibit their reusability. In this work, Zr-based MOF...
