近年来,由于薄层色谱在分离稀土上所具有的优点,不断受到人们的重视。有关薄层色谱法分离稀土元素的论文也有不少报道,其中Specker等人的工作最有成效,在核裂变产物中分离了镧系元素,国内有罗焕光等人利用P_(538)体系对分离镧系元素作了研究,宗巍等人用P_(204)体系分离测定了独居石中的轻稀土元素。我们利用二-(2-乙基己基)磷酸酯(P_(204))—2-乙基已基(2-
In recent years, due to the advantages of thin-layer chromatography in the separation of rare earth, continue to receive the attention of people. Many papers on the separation of rare earth elements by TLC have also been reported. Among them, Specker et al. Work most effectively to separate lanthanides from nuclear fission products. In the domestic research, Luo Huanguang and others used P 538 to separate lanthanum Department of elements made a study, Zong Wei et al. P_ (204) system separation of light rare earth elements in monazite. We used bis (2-ethylhexyl) phosphate (P_ (204)) - 2-ethylhexyl (2-
