Removal of oxyanions from aqueous systems using polymer filtration (water-soluble metal-binding polymers with ultrafiltration)
- Los Alamos National Lab., NM (United States)
The group V-A and VI-A elements exist in the environment as oxyanions. They enter the environment from both agricultural and industrial sources. The Kestersen reservoir hazardous to wildlife. Arsenic and antimony are used in pesticides and as hardners in alloys, bearings, and in storage batteries. All these metals are emitted during smelting operations. We have been able to remove As(V)/Se(V) from the 100 ppm level to very low levels using water-soluble metal-binding polymers with ultrafiltration. Arsenic contaminated drinking water from Europe was treated and the As level was successfully lowered to better than drinking water standards (<0.1 ppm). We will report on the development and testing of new water-soluble polymers for binding oxyanions.
