Graphene oxide-iron oxide based thin film nanocomposite membrane for congo red dye removal and simultaneous salt recovery from aqueous stream.

ABSTRACT: Current work focusses on the synthesis of iron oxide impregnated-graphene oxide incorporated polyvinylidene fluoride based thin-film nanocomposite (TFN) membrane and its application in Congo Red dye removal. Interfacial polymerization with 0.02 wt% graphene oxide significantly improved performance of prepared TFN membranes, achieving over 94% rejection of dye with permeability of 3.6 l/m²·h·bar. Testing performance of the membrane was further validated in the presence of real-life feed wastewater, showing 72% dye rejection over 12 h, while an enhanced 94% rejection was achieved with synthetic dye solution. Superior performance was observed in removal of dissolved solids, conductivity, salinity, nitrate, sulfate and dyes compared to commercial nanofiltration membranes. Effect of
