  New types of acidic organophosphonates, HR with different hydrophobic groups, were synthesized in order to investigate their extraction behavior for heavy rare earth elements (Y3+, Ho3+, and Er3+) from aqueous acidic chloride media. Their physicochemical properties, such as aggregation in an organic diluent and the acid dissociation constants (Ka) in the aqueous phase, were also examined. These rare earth elements were supposed to be extracted according to the stoichiometric relation,This idea and the extraction equilibrium constants (Kex) for each metal ion were evaluated. Both the extraction equilibrium constants and the separation factors (β) between these metal ions were found to be greater than those of commercial extractants. The correlation between the extractability of heavy rare earth elements, the selectivity among these elements and the chemical structures of these extractants are discussed from a qualitative perspective.

  为研究新型酸性有机膦酸酯HR（含不同疏水基团）从水溶液酸性氯化物介质中提取重稀土元素（Y3+、Ho3+和Er3+）的行为，对其进行了合成研究。同时考察了这些萃取剂的理化性质，如有机稀释剂中的聚集现象和水相中的酸离解常数（Ka）。据推测，这些稀土元素的提取遵循化学计量关系，并评估了这一假设及各金属离子的萃取平衡常数（Kex）。结果显示，相比于商业萃取剂，这些萃取剂的萃取平衡常数和金属离子间的分离因子（β）均更大。本文从定性角度探讨了重稀土元素的萃取性能、元素间的选择性以及萃取剂化学结构间的相关关系。
