The high-function sponge realized by compounding nanomaterials, such as Prussian blue nanoparticles and CNT, which have successfully decontaminated radioactive cesium.

The radioactive cesium adsorption sponge wherein the Prussian blue nanoparticles, which has been proven to decontaminate local storage reservoirs contaminated by radiative cesium, are used.


High performance adsorbent for targeting radioactive cesium ion is complexed materials combined with prussian blue nanoparticles(nano-PB) in diatomite (DM) sealed with dispersed carbon nanotubes for preserving formation of nano-PB / DM.
