摘要

本文报告了从工业规模的高浓度液体废物（HLLW）中分离 137Cs 过程中产生的废溶剂中回收 1,3-二辛基氧基钙[4]烯-18-冠醚-6（CC-6）的工艺开发研究。初步工作包括验证概念性工艺设计，并利用模拟溶剂优化工艺参数。然后用实际废溶剂对优化后的工艺进行测试，以回收钙冠-6。这是首次尝试从废溶剂中回收未降解且有可能再次使用的钙钛矿-6，目的是回收价值并减少废溶剂管理负担。

Process development studies on the recovery of caesium specific calix-crown-6 extractant from actual spent calix solution for efficient spent solvent management

This paper reports the studies carried out on the development of a process for the recovery of 1,3-dioctyloxycalix[4]arene-18-crown-6 (CC-6) from the spent solvent generated during industrial scale separation of 137Cs from High Level Liquid Waste (HLLW). Initial works involved the validation of a conceptual process design and optimization of the process parameters with a simulated solvent. The optimized process was then tested with actual spent solvent to recover calix-crown-6. Such a process to recover undegraded and potentially re-usable calix-crown-6 from the spent solvent has been attempted for the first time with the aim of value recovery and reduced spent solvent management burden.
