【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,Pb,Cd,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。更多还原

【Abstract】 Objective:To establish a method for the determination of 5 elements(As,Pb,Cu,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,Pb,Cu,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.更多还原
