Polymer-coated electrode detects PFAS in water
News
25 Nov 2020 | C&EN
Instead of bringing water samples back to the lab for analysis, researchers would like to have a continuous field monitor. ”We knew that electrochemistry potentially would be sensitive and selective enough to detect PFAS, and it’s rather inexpensive,” Dick says.
