Abstract

The process characteristics of a new solid–liquid Cs ⁺ separation from the radioactive liquid waste using a crown ether dicyclohexano-18-crown-6 as an extractant and an ionic liquid of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide were studied. The physicochemical properties of the precipitate containing Cs ⁺ which is an solid–liquid extraction product were investigated to identify the solid–liquid phase separability and Cs ⁺ loading. The Cs ⁺ separation process performances were compared experimentally with those of the conventional adsorption system for pretreatment requirement and the amount of Cs ⁺ waste. It was observed that the solid–liquid separation method using ILs has high Cs ⁺ separation performance especially in the low Cs ⁺ concentration.
