摘要

This study introduces an efficient and cost-effective approach for extracting 224Ra and 228Ra from natural thorium through precipitation and barium carbonate co-precipitation, thereby ensuring a sufficient supply of parent nuclei for 212Pb generator preparation. The carbonate precipitate can be dissolved with a minimal volume of a low-solubility acid, making it an ideal candidate for preparing liquid generators. This study report, for the first time, the co-precipitation of radium from high-purity thorium using barium carbonate, achieving a recovery of radium above 90%. This method exhibits immense potential for the industrial-scale production of 212Pb, marking a significant advancement in the field.
