定量分离单一相邻稀土元素是较难的课题。用液相色谱分离非相邻稀土对或示踪量的个别相邻稀土对,文献曾有些零星报导。为实现四个现代化,对单一稀土含量的测定的要求便日益迫切了,例如为了探讨球墨铸铁中单一轻稀土元素的作用机理,必须知道单一稀土的含量。本文是以聚三氟氯乙烯为载体,以二(2-乙基己基)磷酸为固定相,盐酸为流动相的反相萃取柱色层分离法。在进行了一系列的条件试验后,在利用自制的加压
Quantitative separation of single adjacent rare earth elements is a more difficult issue. The use of liquid chromatography to separate non-adjacent rare earth or tracer of the individual adjacent pairs of rare earth, the literature had some sporadic reports. In order to realize the four modernizations, the requirements for the determination of a single rare earth content have become increasingly urgent. For example, in order to investigate the mechanism of action of a single light rare earth element in ductile iron, it is necessary to know the content of a single rare earth element. In this paper, poly (chlorotrifluoroethylene) as carrier, bis (2-ethylhexyl) phosphate as the stationary phase and hydrochloric acid as the mobile phase reversed-phase extraction column chromatography. After a series of conditioning tests, the use of self-made pressure
