The evaluation of bis-1,2,4-triazine complexants containing eight-carbon, alkoxy-functionalized phenyl substituents at the 3,3′-positions for selective minor actinide extraction in simulated high level waste is reported. The complexant retained chemoselective extraction efficiency of actinides over lanthanides while breaking through the nonpolar diluent solubility and hydrolytic stability barriers that limit many BTP complexants. Thus, we report a BTP complexant that is readily soluble in both kerosene and isooctanol without forming precipitates, emulsions, or third phase after contact with nitric acid and extracts ²⁴¹Am³⁺ from ¹⁵⁴Eu³⁺. Separations and spectroscopic data are reported herein.

一种水解稳定的络合剂，用于在工艺相关稀释剂中与 Ln 分离

报道了在 3,3'-位含有八碳烷氧基官能化苯基取代基的双 1,2,4-三嗪络合剂在模拟高放废物中选择性萃取次锕系元素的评估。该络合剂保留了锕系元素相对于镧系元素的化学选择性萃取效率，同时突破了限制许多 BTP 络合剂的非极性稀释剂溶解度和水解稳定性障碍。因此，我们报道了一种BTP络合剂，它易于溶于煤油和异辛醇，与硝酸接触后不会形成沉淀、乳液或第三相，并从¹⁵⁴ Eu ^{3+中萃取241} Am ³⁺。本文报道了分离和光谱数据。
