| 摘 要： | 目的建立微波消解-电感耦合等离子体质谱法(microwave digestion-inductively coupled plasma mass spectrometry, ICP-MS)测定畜禽粪便中8种金属元素的含量。方法干燥后的畜禽粪便样品经高速球磨仪球磨匀,采用微波消解仪对样品进行消解,消解后的样品用ICP-MS混合模式测定畜禽粪便中的砷、汞、铅、镉、铬、锌、铜和镍等8种金属元素,内标法定量。结果 8种元素检出限分别在0.017～0.64μg/L之间,线性关系良好,相关线性系数r0.999;不同元素的添加回收率为92.0%～101.9%,相对标准偏差为0.9%～5.0%。结论该方法样品前处理简单高效、分析用时短、准确度和精密度高,适用于批量畜禽粪便中多元素的测定。
