| 摘 要： | 采用电感耦合等离子体质谱法(ICP-MS)同时测定地下水中44个元素。结果表明,ICP-MS可同时测定地下水中44个元素,方法检出限为0.002～0.981μg/L,大多数元素的精密度(RSD,n=10)均小于10%,加标回收率在90.0%～110.0%,符合中国地质调查局地质调查技术标准对无机组分测试质量控制的要求。方法应用于直接测定元素浓度范围在ng/L～mg/L级的实际地下水样品,快速、简便,结果准确。

| Abstract: | 44 kinds of elements in underground water were simultaneously analyzed by inductively coupled plasma-mass spectrometry (ICP-MS),which only took about 2 ～ 3 minutes for each sample.The detection limits of the method for the analytes were in the range of 0.002 ～ 0.981 μg/L and the recoveries were 90.0% ～ 110.0% with precision of lower than 10% RSD (n=10) for most of the elements,which satisfied the technical standard requirements of quality control for inorganic analysis in underground water quality survey.The method provides the advantages of low detection limits,high precision and accuracy,high efficiency and has been successfully applied to routine analysis of these elements in groundwater samples. |
