MIT researchers reveal incredible method to remove array of harmful pollutants from water: ‘Most technologies focus only on specific molecules’

Posted by in categories: chemistry, engineering

Researchers at the MIT Department of Chemical Engineering have created a new method of cleaning micropollutants from water, using zwitterionic molecules — i.e., molecules with the same number of positive and negative charges.

Devashish Gokhale, a PhD student and one of the researchers, explained zwitterionic molecules by comparing them to magnets.

“On a magnet, you have a north pole and a south pole that stick to each other, and on a zwitterionic molecule, you have a positive charge and a negative charge which stick to each other in a similar way,” he said in a release by MIT News.
