碱性锌锰电池用锌粉中杂质元素的质谱分析
Determination of impurity elements in zinc powder for alkaline Zn/MnO2 battery by inductively coupled plasma mass spectrometry
摘要
Abstract
An inductively coupled plasma mass spectrometry (ICP-MS) with an octopole reaction/ollision cell (ORS) and shield torch system was employed for the determination of impurity elements in zinc powder for alkaline Zn/MnO2 battery. The elements of Mg,Cr,Mn,Fe,Co, Ni, Cu, As, Mo, Cd,Sb and Hg were determined by introducing the hydrogen gas or helium gas into the ORS to eliminate the interference of multi-element molecules and ions. Sc, Ge, In and Tb were used to correct the matrix interference and drift. Under the optimal conditions,the detection limits of the impurity elements were 0.001 ~ 0.031 μg/L,the relative standard deviation was 0.84% ~ 2.36% ,the recovery of the samples was 91.8% ~ 106.0% .The method was easy,rapid and accuracy.关键词
