The Preparation and Oxidative Properties of Ferrate Ion (FeO4(2-)). Studies Directed Toward Its Use as a Water Purifying Agent. Phase I.

摘要

The use of FeO4(2-) in the treatment of deep-well and Missouri River water has been evaluated with respect to many variables. It is found that the addition of FeO4(2-) effectively reduces the amounts of iron,manganese,cadmium,mercury,lead,cobalt,nickel,arsenic,and boron to values less than the detectable quantities with our instrumentation. This is done with less than 50ppm of added Na2FeO4. For iron removal, 1-2ppm FeO4(2-) removes iron to less than .02ppm giving an easily filterable precipitate. FeO4(2-) is extremely deadly to many river water bacteria as well as to selected strains of laboratory bacteria. Test virus are also highly susceptible to its action and the damage is permanent. It has the further advantage of leaving no residue or residual action after a short reaction period and filtration.
