Fig. 7: Performance of the pristine and graphene oxide-based membranes.

The camera captured images of the (a) Feed, water-in-oil emulsions, (b) permeate of the p-CM membrane, and (c) permeate of the OD-CLGO-N-CM membrane; and histograms showing the (d) permeation fluxes of the feed; and (e) separation efficiencies of ceramic membranes.
