Design of microchannel suitable for packing with anion exchange resins; Uranium separation from seawater containing a large amount of cesium

Ouchi, Kazuki; Tsukahara, Takehiko*; Brandt, A.*; Muto, Yuki*; Nabatame, Nozomi*; Kitatsuji, Yoshihiro

Analytical Sciences, 37(12), p.1789 - 1794, 2021/12

We attempted to scale down a separation process of uranium (U) using the microchip column loaded with anion exchange resin to develop safety and waste-reducing separation technique. The ideal separation performance of U was obtained by the properly design of a microchannel. The concentration of U in seawater as a real-world sample could be quantified with the prepared microchip column. It indicates that the microchip column is sufficiently practical. Compared to separation of U with a general column, the column size was successfully scaled down to $$<$$ 1/5000.

Separation and immobilization of Sr and Cs contained in acidic media by using inorganic ion-exchangers (literature survey)

The present study deals with the survey of inorganic ion-exchangers suitable for separation and immobilization of Sr and Cs contained in acidic high-level liquid waste. For separation and immobilization of Cs, crystalline silicotitanate seems to be the most promising exchanger. For selective separation of Sr, there is no promising exchanger up to now. Sintered ceramics are favorable waste forms of inorganic ion-exchangers. Their stabilities are largely influenced by composition of exchangers, qualities of ceramics and disposal scenario.
