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.
