ICP-MS同时测定松花粉中16种稀土元素

Simultaneous Determination of 16 Rare Earth in Pine Pollen by ICP-MS

摘要:

目的：建立一种快速消解并同时测定松花粉中稀土元素的方法。方法：采用微波消解样品。选择In作内标，电感耦合等离子体质谱法测定松花粉中稀土元素。结果：方法简便、快速、准确，灵敏度高。对于所测元素，校准曲线的相关系数 > 0.9990，回收率范围为90.1%~108.1%，相对标准偏差0.9%~8.6%。结论：松花粉中稀土元素含量可用ICP-MS测定。

Abstract: Objective: A method for rapid digestion and simultaneous detection of rare earth elements in Pine pollen was established. Methods: Rare earth elements in Pine pollen were digested by microwave digestion system and determined by ICP-MS. In was used as the internal standard. Result: The method was simple, rapid, accurate and highly sensitive. The correlative coefficient of the calibration curves was over 0.9990, the recovery factor was from 90.1% to 108.1% and the relative standard was from 0.9% to 8.6% for all the analyzed elements. Conclusions: The rare earth elements in Pine pollen can be simultaneously determined by ICP-MS.
