Abstract
Microsphere layers/nanofibrous membranes decorated with UiO-66-NH2 as a metal-organic framework (MOF) were successfully obtained by one-step coaxial electrospinning. The coaxially spun dense microsphere/wire-like structure and UiO-66-NH2 hydrophilic components with excellent hydration ability enabled the prepared membrane to have excellent static and dynamic adsorption capacity for dyes and oil-in-water emulsion separation performance (adsorption capacity >247 mg/g; separation efficiency >99%). What's more, the membrane can purify complex wastewater dynamically and efficiently (separation efficiency >99%). After the membrane was desorbed in ethanol and methanol, the reversible recovery rate was as high as 98%, indicating its excellent recyclability. In a word, the as-prepared membrane has broad prospects in the remediation of complex polluted water bodies containing dyes-oil.
