Efficient Separation of Oil-In-Water Emulsions with Functionalized Superhydrophilic Graphene Oxide-Chitosan Based Composite Membrane

Wastewater polluted with oil and other compounds poses enormous threats to the human and environments. Highly efficient separation of “oil” and “water” it is very challenging. The present study focussed on effective method for the separation of emulsified oil using superhydrophilic and superoleophobic cellulose acetate membrane. The membrane was fabricated with graphene oxide (GO) and Chitosan (CS) using vacuum-assisted filtration technique. The modified composite membranes have exceptional separation efficiency. The separation efficiency all the emulsified oils 1:4 concentration is more than 95%, that representing the better “oil” and “water” separation performance. The test of antibacterial activity was performed with gram-positive Bacillus cereus and gram-negative E.Coli was investigated by a zone of inhibition was noted. It is found that Graphene and Chitosan composite membrane have the potential to remove oils from the waste water.
