Graphene Based sieve Turns Seawater into Drinking Water


Graphene Based Sieves Makes Seawater Fit For Drinking

It is an unaltered fact that Sea Water is not fit for drinking because of the excess Sodium content in it, but science is developing at a very fast pace and in this 21st century the stalwarts of science and technology have innovated a new technique through which they can separate salt from the sea water and will make them fit for drinking. We cannot drink sea water because of the taste, simultaneously it leadsto several other health problems like high blood pressure and many more.

Our planet Earth is known as the blue planet because it has approximately 71% of water out of which only 3 % of the water is non-saline and hence fit for consuming. Due to this situation, there are people in this world who do not get optimum amount of water to drink and there are many who even die due to the scarcity of drinking water. If the researchers can reduce the percentage of unfit water by making it fit to drink, then that would be a very big gift to mankind.

A team of researchers based in UK have developed a sieve based on Graphene that can remove salt from the sea water and will make it fit for drinking. A team from the University of Manchester had confirmed a fact in 2004 that graphene consists of carbon atoms which are layered singly and are organized in a lattice in the form of a hexagone, due to which this tool is sure to provide promising results with the help of extraordinary properties, which includes unusual strength in the tensile and a high conductor of electricity that ensures this as one of the most potent material to grant assured measures in the past.

The scientists have also declared that it is quite difficult to manufacture such single layered Graphene with the existing technologies. The production cost is also very high and that needs to be supported. The deposition of chemical vapor method won’t be much feasible to support the innovation from all ends. Rather, a very onymous scientist has confirmed that oxides that are to be used in the Graphene can be produced only via a simple method of oxidation in the lab.

Though, he orated it to be simple, but the process is lengthy. This is undoubtedly a very big step to abolish the problems cropping up due to scarcity of drinking water, but the underlying measures are such that cannot be averted and for this, the technique of Graphene is still at stake. Manufacturing of single layered Graphene is not much feasible, instead we can replace it that with oxide Graphene, which will give the same result with less cost of production.

Some problematic zones have been discovered when it comes to Graphene of single layer and these uncomfort zones can be avoided if Graphene of oxide are used in its place. So, in this era using of oxides of Graphene will be much suitable to avoid unnecessary expansions.
