| Abstract | The use of FeO4(2-) in the treatment of seep-well and Missouri River water has been evaluated with respect to many variables. The addition of FeO4(2-) effectively reduced the amounts of iron, manganese, cadmium, mercury, lead, cobalt, nickel, arsenic, and boron to values less than the detectable quantities with available instrumentation. This is done with less than 50 ppm of added Na2FeO4. Any excess FeO4(2-) decomposes in 15-20 minutes (depending on temperature and acidity) precipitating Fe(OH)3 and giving O2 to the system. FeO4(2-) is also extremely toxic to many river water bacteria. The final subject reported is the synthesis of Na2FeO4 by electrolyzing scrap iron. |
