| 摘 要： | 选取了玉米秸秆与籽粒、小麦秸秆与籽粒、烟草等5种不同的植物样品,加入硝酸-过氧化氢,进行敞口消解,消解液中As(75As)采用电感耦合等离子体质谱仪He碰撞模式测定,以72Ge为内标元素。结果表明：2个国家生物成分分析标准物质GBW10011(GSB-2,小麦)和GBW10020(GSB-11,柑橘叶)砷的测定值在标准确认值范围内；在植物样品中加入砷标准溶液,加标回收率在87%~104%之间；方法检出限为0.0055 μg/g,灵敏度较高；对4个植物样品分别重复测定5次,相对标准偏差均小于10%。本文结论认为电感耦合等离子体质谱仪He碰撞模式可以用于测定硝酸-过氧化氢敞口消解植物样品中砷含量,该方法测定结果准确可靠,重现性好,灵敏度高。
