  • Method of separating amorphous iron oxides
    Patent number: 9607721
    Abstract: A method for separating amorphous iron oxides is provided. The method includes steps of sampling, filtering, dissolving and separating, analyzing the solution containing amorphous radioactive iron oxides and analyzing granules containing crystalline radioactive iron oxides. Characteristics of the radioactive iron oxides during various periods are acquired to solve the radiation buildup problem. Parameters for improving water quality and chemistry performance indicator are thus provided. Crystalline deposits are separated while the dissolving rate of radioactive iron oxides reaches more than 90%. The present invention does not use complex utilities, is easy to use and has a low operation cost for fast analysis.
