| 摘 要： | 为建立同时检测干制水产品中铅、砷、铝、铬、铁、铜金属残留的电感耦合等离子体质谱(Inductively coupled plasma mass spectrometry,ICP-MS)方法。选择自动石墨消解仪对样品进行消解,消解完全后,利用ICP-MS对样液进行检测,内标法定量分析。结果显示:铅、砷、铝、铬、铁、铜元素浓度在0. 25～25μg/L范围内线性良好,相关系数(R2)均大于0. 990;检测限:铅0. 02μg/L、砷0. 08μg/L、铝0. 12μg/L、铬0. 10μg/L、铁0. 03μg/L、铜0. 05μg/L;加标回收率在84. 0%～108. 4%之间;方法重复性RSD(n=6)低于10%。该方法操作简单、准确度高、检测限低、重复性好,可以用于干制水产品中的金属元素检测。
