Destruction of pfas in the presence of silica |
| abstract |
We have discovered that heating PFAS in the presence of silica resulted in destruction of over 90% of PFAS under surprisingly mild conditions. Experimental results are presented showing that the reaction occurs along with etching of the silica glass, presumably caused by HF created during the reaction or in previous reactions. The methods of destroying PFAS are especially effective for treating relatively concentrated solutions such as those commonly encountered in AFFF waste stock and cleanup near fire-fighting training sites, as well as concentrated waste solutions from industrial sites involving the manufacture or application of PFAS. |
