Kottayam :

In a breakthrough invention , a research student at the MG University  here developed a method to remove toxic dyes and Nano particles from water using cellulose based Nano filters made from agro waste. It was Deepu Gopakumar, 28-year-old research student of Nano Science technology at the varsity who made this important invention which will help in cost effective purification of water in future. A green approach for purification of water is also made possible as organic solvents are not needed in this new method.

Deepu developed a Nano cellulose based Nano fibrous membrane from agro waste (pineapple, banana, coir etc.) for the removal of toxic textile dyes and nanoparticles from water. Currently, most of the surface modifications of cellulose nanofibers are done using toxic organic solvents. The new method is the first one where the surface modifications of cellulose Nano fibers is done through non solvent assisted procedure.

Deepu did his research under the supervision of Sabu Thomas and Nandakumar Kalarikkal at the International and Inter University Centre for Nano science and Nanotechnology (IIUCNN), MG University. The research also had support of Federal University of Uberlandia, Brazil, under the supervision of Daniel Paiquini, said MG Vice Chancellor Babu Sebastian. The results of the study were recently published in ACS sustainable energy and engineering. American Chemical Society  (ACS) is a scientific society based in the United States that supports scientific inquiry in the field of chemistry.

According to Deepu, the bed developed from the agro waste which is used for purification of water can be continuously used for six months after that it has to be cleaned. Since the membrane does not have any organic solvent, minerals are not lost from the water.

Babu Sebastian said that the University will apply for a patent for the invention. Research guides Sabu Thomas and Nandakumar said that the University will start producing it commercially within a year after finding a business partner. The university is also planning to develop miniature models which can be connected to the water taps. According to initial studies the cost of purifying water which costs around Rs 5 for a litre can be reduced to Rs 2 using the new method. It can also be sued for sea water purification.
