Graphene could work wonders in water purification
Graphene could work wonders in water purification.
However, an innovative solution to this problem was proposed in this month’s issue of journal Nature Nanotechnology.
The authors, who belong to a group in the National Graphene Institute at the University of Manchester, developed graphene-oxide membranes capable of controlling pore size.
In order to avoid swelling, the sheets were stored under high humidity conditions and embedded in epoxy resin.
“This is the first clear-cut experiment in this regime.
We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes.” The innovation is a low-cost, sustainable and reliable alternative to current bulky desalination systems.
When brought to fruition, it could be a game-changer in countries with poor access to drinking water.
This development could have far-reaching consequences including improving child health and empowering women who currently spend a significant part of their days gathering water.
Additionally, the United Nations forewarns that by 2025, 14% of the world will suffer from water scarcity.
Tunable graphene-oxide filters could potentially save the world from the impending water crisis.
