| 摘 要： | 目的：建立微波消解-电感耦合等离子体质谱（ICP-MS）法同时测定人发中锰、钴、镍、铜、锌5种必需微量元素的方法。方法：采用硝酸-过氧化氢消解体系，微波消解法处理样品，直接用ICP-MS同时测定上述5种元素。结果：方法的检出限为0．007-0．036μg/L，标准曲线线性关系良好（r〉0．9999），相对标准偏差（RSD）小于3％，对人发标准物质的测定值均在标准参考值范围内。结论：应用微波消解-ICP-MS法分析发样，方便快捷，灵敏度高，线性范围宽，准确度好。 |

| Abstract: | Objective:A method of determination of five essential trace element including Mn、Co、Ni、Cu、Zn in hair by microwave digestion and ICP-MS was established.Methods:The sample was dissolved directly by microwave digestion with HNO3-H2O2 and the 5 elements were determined by ICP-MS.Results:Detection limits of the 5 elements were 0.007~0.036μg/L and correlation coefficient is larger than 0.9999.RSD of the method was less than 3%.The proposed method was used in the analysis of a hair standard reference material and the result was in conformity with standard values.Conclusion:This method of hair analysis is rapid,hypersensitized and accurate. |
