Publication number: 20210346894Abstract: The present invention relates to a method of separating fine particles in soil using cationic magnetic nanoparticles, and more particularly, to a method of separating fine particles (clay, silt, etc.) that have adsorbed contaminants such as heavy metals or radioactive nuclides in soil using cationic magnetic nanoparticles. According to the present invention, contaminants such as heavy metals or radioactive nuclides selectively or irreversibly adsorbed to fine particles (clay, silt, etc.) in soil may be economically and efficiently separated. Therefore, the present invention may be effectively used to restore soil in residential areas that are contaminated with radioactive nuclides in serious accidents such as the Fukushima Daiichi nuclear disaster as well as facility sites contaminated with heavy metals or radioactive nuclides.Type: ApplicationFiled: September 18, 2019Publication date: November 11, 2021Inventors: Il Gook KIM, Chan Woo PARK, Hee Man YANG, Kune Woo LEE, In Ho YOON, Bum Kyoung SEO

Patent number: 11059082Abstract: 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.Type: GrantFiled: October 9, 2018Date of Patent: July 13, 2021Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Il Gook Kim, Kune Woo Lee, Chan Woo Park, In Ho Yoon, Hee Man Yang, Bum Kyoung Seo
