  • Publication number: 20200030771
    Abstract: Provided is a radionuclide absorbent, a method of preparing the same and a method of removing a radionuclide using the same. The radionuclide absorbent, compared to conventional zeolite, may more selectively remove radioactive cesium (Cs+) and/or strontium (Sr2+) ions even in the presence of various competitive ions (e.g., Na+, K+, Mg2+, and Ca2+) in groundwater or seawater. In addition, the radionuclide absorbent may be prepared by a simple method of thermally treating a mixture of sulfur and zeolite, and thereby, sulfur may be uniformly dispersed in zeolite.

  • Publication number: 20190275573
    Abstract: The present invention relates to a method for removing cesium in a clay mineral using hydrogen peroxide. According to the present invention, cesium in a clay mineral is removed using hydrogen peroxide, which serves to induce interlayer expansion of the clay mineral to allow a cation to easily enter an interlayer of the clay mineral, and thus cesium desorption efficiency can be further improved. Also, the method according to the present invention can be efficiently used to restore soil in residential areas widely contaminated with a radionuclide when a major accident such as Fukushima nuclear accident occurs as well as various sites of atomic energy facilities contaminated with a radionuclide. Also, since radiation-contaminated soil is treated with only hydrogen peroxide and cations, secondary environmental pollution caused by wastes can be significantly reduce and the waste disposing cost can also be saved.
