摘要

目的: 建立电感耦合等离子体光谱法/质谱法(ICP-AES/MS)测定自然铜不同炮制品中砷(As)、铅(Pb)、铜(Cu)、镉(Cd)和汞(Hg)含量检测方法

为制定As

Hg等有害元素的限量标准提供依据。方法: ICP-AES/MS检测经微波消解法的供试品

通过校正曲线计算含量。结果: 5种元素标准曲线线性关系良好

r=0.999 2~0.999 8

回收率符合痕量分析要求。结论: 方法灵敏度高

检测限低

分析速度快

分析精密度高。

Abstract

Objective:To establish a method for the determination of 5 elements (As

Cd and Hg) in different pocessed products of pyrite by inductively coupled plasma atomicemission spectrometry/mass spectrometry(ICP-AES/MS)

in order to provide a basis for thelimit standards of As

Cd and Hg and other harmful elements. Method: Five elements of the digested samples were determined by ICP-AES/MS simultaneously

and the contents were calculated by calibration curves. Result: Good linearity of calibration curves was obtained for ICP-AES/MS assay

the accuracy and the recovery met the requirement of trace analysis. Conclusion: The method is highly sensitive

rapid

accuracy and offered with low LOD.
