Doping calcium ions in metal sulfide to enhance adsorption of cesium ions in acidic wastewater.

Caption

Pusan National University researchers developed a new calcium (Ca2+)-doped ion exchanger for the removal of radioactive cesium ion (Cs+) from acidic nuclear powerplant wastewater. The adsorbent leverages an otherwise problematic excess of protons in acidic wastewater to leach out Ca2+ ions, facilitating Cs+ adsorption.
