A team of researchers from IASST (Institute of Advance Study in Science & Technology) Guwahati has developed a new ecofriendly biopolymer based on nanotechnology to purify water. The new technology may be useful for civic and municipal water treatment units to generate potable water. The nanoparticles in biopolymer play a role in removing magnesium and calcium using ion exchange process. The material of the polymer is green and biodegradable with water-softening ability
