原子吸收法测试钡天青石中微量镁、锰的研究

Determination of Trace Mg and Mn in Celestine by AAS

本文研究了用原子吸收分光光度法测定钡天青石中微量镁、锰简捷新方法。钡、锶、钠、钾等离子干扰 ,可加入适量的 L a Cl3 为抑制剂消除干扰。试样用 HF与 HCl O4分解 ,用 HCl调节 1%的酸度后 。

A simple method for the determination of trace of Mg and Mn in celestine by AAS was studied. The interference of Ba, Sr, K and Na ions were eliminated by adding suitable amounts of the restrainer. The sample was decomposed by HF+HClO 4,and the solution containing LaCl 3 and acetone was adjusted to 1% hydrochloric acid medium, the Mg, Mn was directly determined by AAS.
