The process of converting sea water into potable water can be done using Graphene Oxide.
The Graphene oxide (GO) membranes can be used to filter common salts in sea water while allowing water to pass through on a commercial scale.
However, there is a problem associated with the use of Graphene Oxide. The membranes have a tendency to slightly swell when immersed in water and this increased spacing between successive sheets allows smaller salts to flow through the membrane along with water without being filtered.
Recently, the researchers has addressed this problem by developing Graphene Oxide membranes that do not swell when immersed in water.
They have achieved this through having a certain interlayer spacing by storing the membranes in high humidity and then physically restraining the membrane from swelling.
This altered the rate at which water permeated through the membranes and efficiency of desalination process has increased.
