摘要
本文研究了三价镅、锔、镨和钕与2-羟基-2,4-二甲基戊酸的络合作用。在pH=4.00,μ=0.5(NaClO_4)和25℃条件下,用静态阳离子交换法得到了各级稳定常数。指出了2-羟基-2,4-二甲基戊酸(HDMVA)可望成为三价镅、锔分离的优良淋洗剂。
The stability constants are reported for the 2-hydroxy-2,4-dimethylvaleric acid (HDMVA) complexes of Am(Ⅲ), Cm(Ⅲ), Pr(Ⅲ) and Nd(Ⅲ) by static cation exchange at 25℃, μ= 0.5 (NaC1O4) and pH = 4.00.According to the stability constants of complexes, HDMVA can be a good eluant for the cation exchange separation of Am(Ⅲ) and Cm(Ⅲ).
