Pusan National University researchers have developed high-adsorption capacity magnesium phosphates for highly efficient capture of radionuclide cesium

Caption

Removal of the toxic radionuclide Cs+ from nuclear power-plant wastes is a huge challenge. Thus, there is an urgent need to remove Cs+, possibly using a phosphate-based adsorbent. To this end, researchers have synthesized dittmarite-type phosphates, KMP (KMgPO4⋅H2O) and NMP (NH4MgPO4⋅H2O), that contain readily exchangeable ions owing to their layered structure. The ion exchange and dissolution-precipitation enabled record-high adsorption capabilities of KMP and NMP for Cs+ that are higher than those of standard adsorbents.
