Adsorption removal of cesium from drinking waters: A mini review on use of biosorbents and other adsorbents

•Studies on adsorption removal of cesium from water are reviewed.•Minerals, biosorbents, and synthesized composites were used as adsorbents.•Demonstration tests were reported to highlight the points raised.•Feasibility of using Prussian blue (PB) for large scale application is discussed. Radiocesium (Cs) removal from waters becomes an emerging issue after the Fukushima Daiichi Nuclear Power Plant Disaster, during which a total of approximately 3.3×1016Bq Cs was released to contaminate the environment. This mini-review provided a summary on literature works to develop efficient adsorbent for removing Cs from waters. Adsorbent made of raw and modified minerals, composites particles, and biosorbents that are highly specific to Cs in the presence of other alkali and alkali earth metals were summarized. Development of Prussian blue (PB) nanoparticles on Cs removal and its potential use in drinking waterworks was discussed. This review is a unique report for adsorption removal of Cs from contaminated waters.
