The most trusted water purifier throughout the world is activated carbon. While activated carbon can rid water of several organic pollutants, it can take hours for the purification to take place. Well, not any more. A group of US Scientists led by Will Dichtel, have discovered a glucose based polymer called β-cyclodextrin that can get rid of the pollutants 15 – 200 times faster than activated carbon. Restoring the purifying power of β-cyclodextrin is also cheaper and easier than that of activated carbons.
The details are outlined in a paper published on Nature magazine. Dichtel said, “What we did is make the first high-surface-area material made of cyclodextrin. We knew that [water filtering] would be a likely application if we were successful. We were definitely pleasantly surprised with just how good the performance is.” Dichtel hopes that this discovery can lead to low expense yet highly effective water purification.
