| 摘 要： | 探讨了P-538萃取钪的条件。和Th~(4 ),Ce~(4 )相似,P-538对钪有极好的萃取能力,即使在高酸下也近于完全萃取,因而可用于钪与其它元素(除Th~(4 )与Ce~(4 )外)的分离,萃合物的组成经测定为Sc(HA)_3。

| Abstract: | P-538, monomyristyl phosphate, is a good extractant for scandium.The extraction is nearly complete even at the acidity is as high as8 mol/L HC1. This method may be used for separating and concentratingscandium from many coexisting elemens (rare earths, alkaline earths,uranium and iron) except tetravalent metals (Ce~(4 ), Th~(4 ) etc). The com-position of the extracted adduct was comfirmed as Sc(HA)_3 by experi-ments. |
