Development of superhydrophillic tannic acid-crosslinked graphene oxide membranes for efficient treatment of oil contaminated water with enhanced stability

摘要: Abstract In the present age of industrialization, oil contamination in waste water has become a huge global concern due to its several negative impacts on human health and aquatic ecosystem. order address this problem, novel oleophobic super-hydrophilic graphene-based membrane been developed using simple cost-effective vacuum filtration methodology. Prior developing membranes, graphene oxide (GO) sheets were crosslinked with tannic acid (TA) molecules improve their mechanical surface properties. To obtain structural morphological information membranes constituents, Field Emission Scanning Electron (FE-SEM) microscopy, X-Ray Diffraction (XRD), FTIR spectroscopy Raman was used. When tested simulated oilfield effluent samples, these exhibited significant reduction values chemical oxygen demand (COD), total dissolved solids (TDS), suspended (TSS) turbidity demonstrating low-oil adhesion preferable rejection rates. Moreover, such are highly stable which can withstand pressure filtration. way, TA GO robust efficient way treat contaminated released from various industries be reused for numerous further applications.
