For the separation of Americium and Curium, solvent extraction of Am, Cm and lanthanide using mono, bi-dentate and bite angle tunable phosphorus ligands were investigated. The separation between minor actinide and lanthanide were achieved by bidentate phosphorus ligand such as Bis(diphenylphosphono)methane. In the all extractants, no large difference of distribution ratios between Am and Cm were obtained.

为了分离镅和Curium，研究了单齿、双齿和咬角可调磷配体对Am、Cm和镧系元素的溶剂萃取。双齿磷配体如双（二苯膦）甲烷实现了微量锕系元素与镧系元素的分离。在所有萃取剂中，Am和Cm的分布比例差异不大。
