Preparation of No-Carrier-Added ¹⁷⁷Lu by DGA Resin Assisted Cyclic Elution

Graphical Abstract

Abstract

Abstract

A preparation process of No-Carrier-Added (NCA) ¹⁷⁷Lu in China Mianyang Research Reactor (CMRR）was investigated. In this work, the key component of the process is DGA resin column which can adsorb Yb(Ⅲ) and Lu(Ⅲ) metal ions in the eluent was added to the purification process of ¹⁷⁷Lu. The eluent “on-line” cyclic elution of lanthanide resin column was realized through special flow path connection. The tracer test showed that this technology can effectively reduce the volume of radioactive acid waste liquid generated from purification process of ¹⁷⁷Lu. The technology was verified in three batches production, and the primary separation stage reduced the volume of waste liquid above 86%. The NCA ¹⁷⁷Lu product prepared by cyclic elution process meets the quality requirements.
