五大连池矿泉泥中无机微量元素的测定

The Determination of Inorganic Trace Elements in Mineral Spring Mud of Wudalianchi

本文采用原子吸收分光光度法对五大连池矿泉泥中的无机微量元素进行测定。试样用 HF—HNO_3进行溶解,并讨论了 HCl、HNO_3对试样中金属元素溶解性的影响。该法的变异系数在4.3%以内,回收率在80%以上。

In this pater,Atomic Absorption Spectrometry was applied to the determination of Inorganic trace elements in min- eral spring mud of Wudalianchi.The samples of mineral spring mud were dissolved with HF-HNO_3,and the effects of HCl: HNO_3 the dissolution of inorganic elcments were disscussed,It proves that this method has high accuracy,good precision and high recovery.
