Abstract
Tetracycline (TC) contamination in water has progressively exacerbated the environmental crisis. It is urgent to develop a feasible method to solve this pollution in water. However, polluted water often contains oil. This paper reported a glass fiber (FG)-assisted polyvinylidene fluoride (PVDF) hybrid membrane with dual functions: high TC degradation efficiency in emulsion and oil-water separation. It can meet the catalytic degradation of tetracycline in complex water. This membrane was decorated by coating the glass fiber with PVDF solution containing hydrophilic graphene oxide hybridized NH2-MIL-101(Fe) particles. Moreover, due to its strong mechanical strength enhanced by the glass fiber, it can be reused as TC degradation catalysts for dozens of times without cracking. Thanks to the hydrophobicity of PVDF and the surface pore size of MOFs, the prepared membrane showed a good oil-water separation performance. Besides, the hydrophilic graphene oxide (GO) and NH2-MIL-101(Fe) improved the membrane’s anti-fouling performance, allowing it to be reused as the separation membrane. Therefore, the outstanding stability and recoverability of the membrane make it as a fantastic candidate material for large-scale removal of TC as well as oil-water separation application.
Highlights
We reported a simple method to construct a glass fiber (FG)-assisted polyvinylidene fluoride (PVDF) hybrid membrane with certain hydrophobicity and strong mechanical strength by coating the glass fiber with PVDF solution containing hydrophilic graphene oxide hybridized NH2 -MIL-101(Fe) particles (named GO/NH2 -MIL-101(Fe)/PVDF/FG
The final membrane has a brown appearance caused by the existence of NH2 MIL-101(Fe) catalysts, and its surface is smooth and dense, both of which are beneficial for the following study
The XRD pattern diffraction peaks of the original PVDF membrane appear at 20.11, which is consistent with the final membrane

Human life is inseparable from water, which is the source of life of all things. With the rapid development of industry and medical technology, various pollutants discharged by people make the water environment pollution more and more serious, and the pollution components are becoming more and more complex, which seriously threatens biodiversity. The focus of this study is to realize the degradation of tetracycline in sewage and oil-water separation
