北京理工大学珠海学院 2020 届本科生毕业论文电感耦合等离子质谱法快速检测豆类及其制品中铅镉等重金属残留的方法研究电感耦合等离子质谱法快速检测豆类及其制品中铅镉等重金属残留的方法研究摘要建立电感耦合等离子体质谱（ICP-MS）法快速检测豆类及其制品中铅镉等重金属残留的方法，样品经过微波消解法、赶酸处理后用 ICP-MS 进行测定，以蒜粉标准物质为质控标准物质，通过加标回收试验来验证方法的精确度。实验结果：加标回收率稳定在由低到高分别稳定在 82.4%-116.22%范围内，相对标准偏差 RSD 为 0.58%-9.45%，标准物质测定值均在标准参考范围内，表明该方法准确简便、灵敏、可靠、快速，适用于豆类及其制品中铅镉等重金属的检测。关键词：电感耦合等离子质谱法，重金属，豆类及其制品，微波消解法北京理工大学珠海学院 2020 届本科生毕业论文Rapid detection of heavy metal residues such as lead and cadmium in legume and its products by inductively coupled plasma mass spectrometry (ICP-Ms)AbstractEstablish ICP-Ms method for rapid detection of lead and cadmium in beans and its products such as heavy metal residues, the method of sample after microwave digestion using nitric acid, driven by icp-ms determination after acid treatment, garlic powder standard substance for the quality control standard, by standard addition recovery test to verify the accuracy of the method. The result: standard addition recovery rate steady at from low to high were stable at 82.4% - 116.22% range, relative standard deviation RSD was 0.58% - 9.45%, standard substance measurements are within the scope of the standard reference, show that the method is simple, rapid, sensitive, reliable, accurate is suitable for analysis of heavy metals such as lead and cadmium in beans and its products.Key words：Inductively coupled plasma mass spectrometry，Heavy metal，Beans and soy products，Microwave Digestion Method. 北京理工大学珠海学院 2020 届本科生毕业论文 目 录1 绪 论11.1 研究背景11....
