化学分离-火花源质谱法测定高纯氧化钪中杂质元素

Determination of Trace Amounts of Elements in High-Purity Scandium Oxide by Chemical Separation-Spark Source Mass Spectrometry

利用Sc^(3-)与SO_4^(2-)形成络阴离子后强烈吸附在强碱性阴离子交换树脂上的性质,分离掉大部分基体钪后,留下一小部分钪作基体。定量加入内标,利用火花源质谱单曝光法测定杂质元素。

After a great deal of matrix Sc is separated by the strongly basic anion exchange resin to absorb the complex of Sc and SO42-,small residual Sc is used as matrix. Internal standard is added, impure elements are determined by spark source mass spectrometry single exposure method.
