The feasibility of separating americium from curium and the lanthanides was studied in batch solvent extraction experiments using an organic solvent composed of 0.01 mol L⁻¹ 2,9-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzotriazin-3-yl)-1,10-phenanthroline (CyMe₄BTPhen) in the ionic liquid Aliquat-336 nitrate [A336][NO₃] from feed solutions containing N,N,N’,N’-tetraethyl diglycolamide (TEDGA), stable lanthanide ions and tracers of ²⁴¹Am, ²⁴⁴Cm, and ¹⁵²Eu. The combined use of a lipophilic and a hydrophilic ligand with opposite selectivity for Am(III) vs. Cm(III) and Ln(III) allowed the separation of Am(III) from Cm(III) and Ln(III) from moderate acidic feed solutions (1 mol L⁻¹ HNO₃, SF_Am/Cm = 3.1–3.9, SF_Am/La > 75, SF_Am/Eu ≥ 3000).

在间歇溶剂萃取实验中，研究了使用0.01 mol L ^-1 2,9-双（5,5,8,8-四甲基-5,6,7，来自含N，N的进料溶液中的离子液体Aliquat-336硝酸盐[A336] [NO ₃ ]中的8-四氢-1,2,4-苯并三嗪-3-基）-1,10-菲咯啉（CyMe ₄ BTPhen）N'，N'-四乙基二甘醇酰胺（TEDGA），稳定的镧系离子和²⁴¹ Am，²⁴⁴ Cm和^152的示踪剂欧洲联盟。对Am（III）与Cm（III）和Ln（III）具有相反选择性的亲脂性和亲水性配体的组合使用可将Am（III）与Cm（III）和Ln（III）从中等酸性分离进料溶液（1 mol L ^-1 HNO ₃，SF _{Am / Cm} = 3.1–3.9，SF _{Am / La} > 75，SF _{Am /} Eu≥3000 ）。
