Abstract:
Background & Aims of the Study: In this study, Metal Organic Frameworks (MOFs) were synthesized as an additive for the preparation of mixed-matrix membranes. MOFs were investigated by FTIR, XRD and FE-SEM techniques.
Materials & Methods: Synthesized MOFs were prepared via the hydrothermal method. The effect of MOFs on the morphology and property of the polyethersulfone (PES) membranes was examined using scanning electron microscopy (FE-SEM). The membranes were characterized by rejection of salt solutions, removal of heavy metals and dyes rejection.
Results: Results show that membrane containing 5 wt% of MOFs provides better hydrophilicity, flux, antifouling and rejection properties and change on the aforementioned characteristic properties was studied for this membrane. The results suggested that the water flux of membrane increased to 190 L.m-2 h-1 which related to 7 wt% membrane as well as the highest rejection for different heavy metals and dyes were related to 5 wt% MOFs in mixed matrix membranes.
Conclusion: Based on the results, hydrophilicity, water flux, and antifouling properties were improved by hybrid membranes.
