摘    要:采用电感耦合等离子体质谱法测定洋葱中重金属的分布,用硝酸-过氧化氢作消解液, 微波消解法处理样品,ICP-MS 法测定洋葱皮和肉中砷、铅、汞3种重金属元素的含量。测定结果的相对标准偏差RSD< 5.1%, 加标回收率为91.1%~104.9%, 检出限为0.007 2~0.087 ng•g-1。该方法具有操作简便,快速,灵敏度高,准确度好和多种元素同时测定等优点。

关 键 词:电感耦合等离子体-质谱  洋葱  重金属

Abstract:Heavy metals in onion skin and pulp were studied by ICP-MS. The samples were digested by microwave assistedly with nitric acid-hydrogen peroxide. The contents of As, Pb and Hg in onion skin and pulp were measured by ICP-MS. The RSD is less than 5.10% and the recoveries are in the range of 91.1%-104.9%. The determination of limits are 0.007 2-0.087 ng•g-1 .This method is fast, stable and accurate. It is suitable for determination of some heavy metals in onion skin and pulp.
Keywords:ICP-MS  onion  heavymetal
