Abstract
High concentration of Cs is present in high-level radioactive waste. It is well-known that Cs is an alkali element and difficult to extract completely into an organic phase. Crown ether compounds are widely available for Cs extractants; DtBuDB18C6 (di-t-butyl-dibenzo-18crown6), was used in this study. Organic solvents used for the industrial applications, such as n-dodecane and 1-octanol, have low solubility concerning the compound; other solvents were employed and tested. In this study, ketone-, ether-, and estertype solvents showed high solubility for DtBuDB18C6 and DtBuDB18C6, when dissolved in ketones and alcohols, exhibited relatively high Cs distribution ratios (D(Cs)), closely to 10.
期刊介绍：
Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
