Dr. Ayse Asatekin Created Membrane that Filters Fluoride out of Water

Dr. Ayse Asatekin, an associate professor of chemical and biological engineering at Tufts University, found a solution to filtering fluoride out of water. In the new study, Asatekin’s lab created a self-assembled, cross-linked zwitterionic copolymer membrane that separates fluoride out of water while keeping chloride in. As water passes through the membrane, tiny holes use special chemical bonds — zwitterionic ones — to leave fluoride behind.
