摘要
以^(151)Eu作稀释剂,质谱同位素稀释法(IDMS)测定了粉煤灰中痕量Eu。通过降低Eu空白获得了较低的检出限。方法检出限为8.7×10^(-10)gEu,精密度为±2%。
Trace amount of Europium in coal fly ash has been determined by isotope dilution massspectrometric method by the author. The detection limit which can be reduced by lowering theEu blank, and the precision of the method are 8.7×10^(-10) and ±2% respectively.
