| abstract | 1,184,866. Radiation treatment of ferrous solutions. UNITED STATES ATOMIC ENERGY COMMISSION. 26 Sept., 1968 [3 Nov., 1967], No. 45778/68. Heading C1A. Acidic, aqueous solutions containing ferrous iron compounds are treated to remove the same, and precipitate ferric oxide, by (a) exposing the acidic aqueous solution containing ferrous iron compounds, having a pH of 6À0 or below, to an ionizing irradiation field having an intensity of at least 1000 rads/hr., while passing air through the solution, until all the ferrous compounds are converted to ferric compounds; and (b) contacting the solution containing ferric iron compounds with calcium carbonate to precipitate Fe2O3. The acidic aqueous solution may be mine waste water, and CaCO3 may be dispersed in the solution during irradiation. Electron beams, proton beams, X-rays and gamma rays are mentioned as examples of the ionizing radiation. |
