Colorado School of Mines Associate Professor of Civil and Environmental Engineering Chris Higgins was recently interviewed for an article in Chemical Engineering News on how polymers can help remove contaminants from drinking water. The article, " Polymer network captures drinking water contaminant," focuses on how cross-linked cyclodextrin removes perfluorinated chemical PFOA from water. From the story: To purge these perfluorinated chemicals from water, engineers primarily use granular activated carbon as an adsorbent. … Other options for removing these compounds include reverse osmosis ....
