Abstract. This work was focused on the promising inorganic and ligand immobilized conjugate materials for selective and high capacity of radioactive cesium (Cs) removal from radioactive liquid waste in Fukushima after an accident at Daiichi Nuclear Power Plant hit by the Great East Japan Earthquake and tsunami on 11 March 2011.

2018-4-5 With simple filtering for the removal of radioactive cesium, PB/PAN showed high removal efficiency (87 ± 3%) within 10 s for 10 mL of 137 Cs solution (1000 Bq L −1). In addition, the 137 Cs removal by PB/PAN showed high removal efficiency (70 ± 2%, after 1 h), even in the actual seawater medium (1000 Bq L −1 of 137 Cs).

Radioactive cesium loaded on BLB is relatively immobile under neutral and alkaline conditions Waste materials that contain more than 8,000 Bq/kg of radioactive cesium are governed under regulation by the Japanese Ministry of Environment (Ministry of Environment, 2013, [ iii ]), which prompted us to examine desorption of adsorbed radioactive cesium from BLB.

2021-3-12 Selective ion-exchange with zeolites has been considered as one of the most promising means to remove a radioactive isotope of cesium, 137Cs, present in low concentration in seawater. However, there has been no report on the fundamental structure–property relation of zeolite-based Cs ion-exchangers. In this study, we investigate the origin of the selectivity of the radioactive cesium

2020-2-1 Various technologies have been applied to separate radioactive cesium from radioactive wastes, such as chemical precipitation, solvent extraction, membrane separation and adsorption. Crown ethers and calixarenes derivatives can selectively coordinate with cesium ions by ion-dipole interaction or cation-π interaction, which are promising extractants for cesium ions due to their promising

2019-2-28 However, radioactive cesium adsorbed into vegetables from the roots can be removed through cooking or processing with some ingenuity. The table above shows removal rates of radioactive cesium in foods. When boiling vegetables, the longer the boiling time is, the larger the removal rate is. This is considered to be because radioactive cesium in ...

2019-4-16 Radiocesium removal from aqueous solutions is vital yet challenging. As a major fission product of uranium, radiocesium widely exists in radioactive wastewater (Clearfield 2010).Among 30 isotopes of cesium, 133 Cs is the most stable one, whereas 134 Cs (2 year half-life; beta and gamma emission) and 137 Cs (30 year half-life; beta and gamma emission) are the most commonly observed

1998-12-15 Removal of cesium from radioactive waste liquids makes the treatment of remaining solutions much easier. Particularly, if a major portion of the radioactivity of high-level solutions can be separated from the bulk of the solution into a small-volume batch and thereafter the remaining solution treated as a medium- or low-level waste, extremely ...
