Jürgen Weippert

Well, yes, graphene oxide is much more hydrophilic due to polar oxide groups (hydroxides, epoxides, carbonyls making it probably slightly acidic) while reduced graphene oxide should have lost most of these functionalities so I would expect it to behave like some kind of "lame activated charcoal" in your application.

Abhijeet Ojha

I agree with Jurgen, Graphene oxide would definitely show more efficiency towards the desalination property. You can follow the following article as well

Depends on technique... rGO as membrane or rGO as electrode for electrochemical desalination..

Faisal Nazeer

GO is more than rGO for water desalination
