Abstract
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 method, 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 method 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.
