Final Progress Reports

Year:   2004 

This past year Dr. Farrell’s laboratory has been testing several iron oxide based reactive adsorbent media for removing arsenic and chromium compounds from potable water.  In conjunction with PEL Technologies in Canton, Ohio, Dr. Farrell filed a patent application on the reactive adsorbent media.  Current tests are being performed to determine the effect of water chemistry on the performance and longevity of the media.  These laboratory studies are aimed at developing protocols for field testing.  In conjunction with these experiments, the project investigators are performing quantum chemistry simulations to determine the binding energies of arsenic and other oxyanions with ferric oxides.  Ultimately, these studies could lead to a cost effective process for removing arsenic, chromium, and other regulated metals from potable water.
