Solvent extraction of scandium from 1.5 M HCl medium using di(2-ethyl hexyl) phosphoric acid in hexane or benzene selectively separates Sc from the accompanying elements in rare-earth minerals (like monazite, xenotime, gadolinite) and also in geological materials. Acid hydrolysis separation of Nb/Ta-type samples separates Sc from the major matrix elements and the remaining elements do not influence the Sc signal in inductively coupled plasma atomic emission spectrometry or flame atomic absorption spectrometry. To avoid the matrix effect due to sodium that accompanies the analyte using the reported backstripping of Sc from the organic extract by 2 M NaOH, the organic extract was evaporated off leaving the Sc in the residue which in turn was treated with a mixture of HNO3±HClO4, dissolved in HCl (10%, v/v) and made up to a known volume before aspiration in the plasma for estimation. The silica-rich geological materials were dissolved by HF±HCl±H2SO4
treatment and the rare-earth minerals (monazite/xenotime) were digested by H2SO4±HCl followed by dissolution in 1.5 M HCl before applying the solvent extraction procedure. In Nb/Ta-type of samples, Sc was separated from Nb and Ta by acid hydrolysis, involving fusion with Na2O2, dissolution in HCl followed by NH3 precipitation and hydrolysis in HCl. The oxychloride precipitates of Nb and Ta are ®ltered off and the ®ltrates assayed for Sc. The proposed methods have been applied to some international geological reference standards (SY-2, SY-3, MRG-1, Mica-Fe, G-2, GH and ASK-2), rare-earth minerals like monazite, xenotime and gadolinite and also to some Nb/Ta-type samples including reference standards IGS-33 and IGS-34, and the results are compared. Both methods are simple, rapid and accurate, showing a relative standard deviation of less than 1% at the 55 ug/g level and 9.0% (at the 1.0 ug/g).

机器翻译看着恶心不?我给你慢慢翻.先来一句,不过这里边的专业词汇我不能保证对哦,专业术语还是自己再查一下.还真不容易呢.
在己烷或苯环境中用二(2-乙基 已基)磷酸从质量分数为1.5%的盐酸溶液中淬取Sc可以将Sc从采自稀土材料(如独居石,磷钇矿,硅铍钇矿)和地质材料的伴生元素中提取出来.在己烷或苯环境中用二(2-乙基 已基)磷酸从质量分数为1.5%的盐酸溶液中淬取Sc可以将Sc从采自稀土材料(如独居石、磷钇矿和硅铍钇矿等)和地质材料的伴生元素中提取出来.
对Nb/Ta类样本进行酸性水解可以从基质元素中将Sc分离出来,余下的元素不会影响感应偶合电浆原子发射光谱或火焰原子吸收光谱中Sc元素的信号.
为了避免用质量分数2%的NaOH从有机进取物中进行Sc回剥时留在解析物中的钠造成的基体效应,先让有机提取物蒸发,在对浆液进行抽吸用于分析之前,对遗留物中的Sc用硝酸±高氯酸溶加入(10%,v/v)的盐酸溶液中构成一定量的混合溶液进行处理.
进行溶剂萃取前,先将富硅地质材料溶解到HF±HCl±H2SO4溶液中,稀土材料(独居石,磷钇矿)则溶解于H2SO4±HCl溶液中,然后溶于质量分数1.5%的HCl溶液中.在Nb/Ta类样本中,Sc是经酸性水解从Nb和Ta中分离出来的,步骤为：将材料与氢氧化钠一起熔解,然后溶解到盐酸溶液中,最后在盐酸溶液中进行NH3沉淀和水解.
对沉淀物中含Nb和Ta的氯氧化物进行Sc分析.（这个单词没有的话,不好翻译的）.
上述方法已经经申请成为国际地质学(SY-2,SY-3,MRG-1,Mica-Fe,G-2,GH 和 ASK-2),稀土材料如独居石、磷钇矿和硅铍钇矿等的参考标准,同样还被申请成为了一些Nb/Ta类型样本的参考标准如IGS-33和IGS-34.上面的方法和样品都比较简单,快速且准确,其相对标准差在55 ug/g和 9.0%(1.0ug/g)的水平上不超过1%.
