Excellent.
I could imagine that the graphene would get fouled with purifying impure water sources.  However, it sounds like it has a good potential for alcohol purification, which will be important for biofuels in the future.

I agree: there is an article about biofuels in Scientific American - August 2011, which talks about the high energy involved in the distillation phase of fermented ethanol, and this large amount of energy is one of the main reasons ethanol biofuel economy seemed unachieveable.
This property of graphene oxide makes us hope again!
