摘要：

2,6-Di(5-alkyl-1,2,4-triazol-3-yl)-pyridine and 2,6-di(5,6-dialkyl-1,2,4-triazin3-yl)pyridine type compounds extract Am(III) 2-bromohexanoate and nitrate from acidic solutions (less than or equal to 1 M HNO3) with an appreciable efficiency and selectivity, yielding Am(III)/Eu(III) separation factors of less than or equal to 150.
