矿石中微量钪的测定,由于没有高选择性和高灵敏度的方法,分析手续繁杂冗长。特别当试样含有大量钍、铀,锆(铪)、钛和稀土元素时,更增加分析的困难。钪与铬天青S和氯化十四烷基二甲基苄基胺于微酸性介质中形成的三元络合物,具有很高的灵敏度,但是选择性仍然不好。本文试验钪与 Trace determination of scandium ore, due to the lack of high selectivity and high sensitivity of the method, the analysis of complex procedures lengthy. Especially when the sample contains a lot of thorium, uranium, zirconium (hafnium), titanium and rare earth elements, but also increase the difficulty of the analysis. Scandium and chrome azure S and tetradecyldimethylbenzylamine chloride in slightly acidic medium formed ternary complex, with high sensitivity, but the selectivity is still not good.
