本文研究了双（2，4，4-三甲基戊基）次膦酸（HBTMPP）单独或与三辛基氧化膦（TOPO）、辛基（苯基）-N，N-二异丁基氨甲酰基甲基氧化膦（CMPO）和亚甲基双（二苯基膦）氧化物（MBDPO）三种加合物的氯仿溶液对La、Pr、Eu、Ho和Yb等三价镧系元素的萃取行为。测定了这些体系的化学计量比、萃取常数和分离因子。镧系离子在TOPO（B）、Ln（HL 2）3或Ln（HL 2）2 B存在下被萃取。CMPO和MBDPO均未形成加合物。
The extraction behavior of certain tervalent lanthanides (Ln) such as La, Pr, Eu, Ho and Yb, using a chloroform solution containing bis(2,4,4-trimethylpentyl)phosphinic acid (HBTMPP), either alone or combined with one of three adductants, trioctylphosphine oxide (TOPO), octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO) or methylenbis(diphenylphosphine) oxide (MBDPO), was studied. The stoichiometry, extraction constants and separation factors of these systems were determined. Lanthanide ions were found to be extracted in the presence of TOPO (B), Ln(HL2)3, or as the adduct complexes, Ln(HL2)2B. Neither CMPO nor MBDPO was found to form adducts.
