This study briefly reports characteristics of Fe-montmorillonite. Fe-montmorillonite was used as a simulant of buffer material in which corrosion products of carbon steel overpack, Fe $^{2+}$ , were diffused. We have found that this clay retains Se(VI) for which natural montmorillonite, such as Na+-type and Ca $^{2+}$ -type, has little retentivity.
