“…Several techniques were developed for the extraction of 137 Cs + from water: reverse osmosis [10], coagulation-sedimentation [11], ion-exchange [12], nanofiltration [13], electro-dyalysis [14] and more recently, fibrous zeolite-polymer composites [15]. On the other hand, adsorption is a highly efficient and cost-effective process with very high ion selectivity provided that the right sorbents are used [16].…”

Cesium is a radioactive fission product generated in nuclear power plants and is disposed of as liquid waste. The recent catastrophe at the Fukushima Daiichi nuclear plant in Japan has increased the 137Cs and 134Cs concentrations in air, soil and water to lethal levels. 137Cs has a half-life of 30.4 years, while the half-life of 134Cs is around two years, therefore the formers’ detrimental effects linger for a longer period. In addition, cesium is easily transported through water bodies making water contamination an urgent issue to address. Presently, efficient water remediation methods towards the extraction of 137Cs are being studied. Prussian blue (PB) and its analogs have shown very high efficiencies in the capture of 137Cs+ ions. In addition, combining them with magnetic nanoparticles such as Fe3O4 allows their recovery via magnetic extraction once exhausted. Graphene and carbon nanotubes (CNT) are the new generation carbon allotropes that possess high specific surface areas. Moreover, the possibility to functionalize them with organic or inorganic materials opens new avenues in water treatment. The combination of PB-CNT/Graphene has shown enhanced 137Cs+ extraction and their possible applications as membranes can be envisaged. This review will survey these nanocomposites, their efficiency in 137Cs+ extraction, their possible toxicity, and prospects in large-scale water remediation and succinctly survey other new developments in 137Cs+ extraction.

“…Various chemical separation methods and waste treatment technologies such as adsorption of Cs + by the cucurbit[6]uril-based assembly and biosorbents, , the isotope dilution–precipitation method using sodium tetraphenylborate, extraction with new silica–calix[4]biscrown materials, − hollow fiber supported liquid membranes, , electrodialysis ion exchange using AMP-PAN, and electrocoagulation by using different anode materials (e.g., aluminum, iron, and magnesium) have been adopted for the separation or removal of Cs + ions from the radioactive waste or contaminated surface/groundwater. However, these processing methods are not very useful for the removal of the Cs + with low concentrations.…”

Bismuth oxychloride (BiOCl)-coated electroactive film was fabricated for the separation of cesium ions based on a potential-triggered method. The effects of applied potential, conductive carbon black (Super P Li), and different exposed facets on the adsorption of Cs + ions were investigated. Experiments revealed that the adsorption efficiency gradually improved with increasing the applied potential to −0.7 V. The introduction of Super P Li improved the adsorption rate and increased the separation efficiency. The adsorption behavior followed pseudo-second-order kinetics. Additionally, the electroactive film showed adsorption selectivity for Cs + in preference to Li + , Na + , and Rb + ; seven consecutive adsorption−desorption experiments indicated that the electroactive film is sensitive to potential. The BiOCl nanosheets with exposed (001) facets exhibited a higher adsorption ratio for Cs + removal than the counterpart with exposed (101) facets. It was also found that the separation performance of Cs + ions was best in the neutral condition. It is expected that this BiOCl material can be used as a promising electroactive material for the removal of Cs + ions from contaminated water in the future.
