| 摘 要： | HDEHP萃淋树脂,其载体是苯乙烯二乙烯苯的共聚合物,固定相是HDEHP即二-(2-乙基已基)—磷酸]。这种萃淋树脂的主要优点是萃取容量较大、有机固定相不易脱落、洗脱曲线形状良好,但能否用于矿石中稀土元素的分组,尚未见有报导。本实验选用此种萃淋树脂,以不同浓度的盐酸为流动相,进行了铈组、钇组稀土的分离洗脱条件试验。然后分别加大掩蔽剂,直接用光度法测定各组稀土。

Rapid Determination of Ce- and Y-group Rare Earth in Ores by Chromatographic Separation with HDEHP Extraction Resin |
| |
| Abstract: | An extraction chromatographic method fo: rapid separation of Ce- and
Y-group of rare earth in ores using HDEHP resin has been studied.
The Ce- group was separated quantitatively from Y-group by elution with
50 ml of 0.4 N hydrochloric acid and the Y-group was eluted quantitatively
with 50 ml of 4 N hydrochloric acid. Each component can be determined by
direct photometric method. |
