Shredded polyethylene terephalate commonly known as PET iscoated with an amino acid named CYSTEINE, usually found in dietetic enhancements.Shredded plastic scrap mixed with cysteine is added into the arseniccontaminated water. The mixture acting as a magnet attracts all the toxicarsenic from the water. When plastic-cysteine mixture attracts the arseniccompletely from contaminated water, it is removed. Now arsenic free water isavailable for drinking!!!!
