The development of mixed-matrix membrane incorporated with reduced graphene oxide synthesized using murraya koenigii leaf for oil/water separation

The incorporation of additives, either from organic or inorganic materials, to form polymeric mixed-matrix membrane (MMM) is one of the most common and favoured techniques to improve membrane properties and performance. In this study, reduced graphene oxide (rGO) with a strong effect of hydrophobici...
