Indian scientists developed eco-friendly nanotechnology for water purification

Apr 6, 2016 12:09 IST

The Scientists team from the Institute of Advance Study in Science and Technology (IASST), Guwahati in Assam developed an eco-friendly nanotechnology for water-softening applications.

The report was published online on 30 March 2016 in the joural Nanoscale and the authors are Upama Baruah and Achyut Konwar of IASST

Key characteristics

• The green technology is the first of its kind with potential to act as a biodegradable and green material for water-softening applications

• It can be used in civic water treatment plants for generating potable water.

• The technology is basically a biopolymer, which uses a naturally occurring substance called Chitosan.

• Chitosan is obtained from the hard outer skeleton of shellfish, including crab, lobster, and shrimp. It will used as a backbone for the carbon nanoparticles to sit on during the purification process.

How it works?

In conventional water-softening techniques the synthetic resins are used where as in the newly developed biopolymer, the nanoparticles are the functional parts.

They remove calcium and magnesium components of water through ion exchange which will purify the water.
