New Polymer Could Purify Water In Seconds: Study
NEW YORK: Scientists have developed a new reusable polymer that can remove pollutants from flowing water within seconds, just like air fresheners trap invisible air pollutants in the home and remove unwanted odours.
Researchers have used the same material found in air fresheners, cyclodextrin, to develop a technique that could revolutionise the water-purification industry.
The team, led by Will Dichtel, associate professor at Cornell University in the United States, developed a porous form of cyclodextrin that has displayed uptake of pollutants through adsorption at rates vastly superior to traditional activated carbon - 200 times greater in some cases.
Activated carbons have the advantage of larger surface area than previous polymers made from cyclodextrin - but they do not bind pollutants as strongly as cyclodextrin.
"What we did is make the first high-surface-area material made of cyclodextrin combining some of the advantages of the activated carbon with the inherent advantages of the cyclodextrin," Mr Dichtel said.
"These materials will remove pollutants in seconds, as the water flows by," he said.
