| 摘 要： | 采用微波消解技术- 电感耦合等离子体- 原子发射光谱法(ICP-AES)测定不同产地蕨麻中Ni、Mn、Ti，Cu、B、Ba、Fe、Zn、Na、Ca、Mg 和K 等多种微量元素的含量。结果显示，用HNO3-H2O2 为消解液微波消解处理样品，方法RSD 值均在5% 以下，加标回收率96.6%～113%；在优化实验条件下，各元素互不干扰，可实现多元素的同时测定；青海产蕨麻中微量元素含量较甘肃产蕨麻高，说明元素含量与蕨麻化学生态型相关。

| Abstract: | Samples of Potentilla anserina L.root from different growing areas were analyzed by microwave digestion-inductively coupled plasma-atomic emission spectrometry(ICP-AES) for contents of many trace elements including Ni,Mn,Ti,Cu,B,Ba,Fe,Zn,Na,Ca,Mg and K.A mixture of nitric acid and hydrogen peroxide was used for microwave digestion of samples.Results showed that the method exhibited a spike recovery range of 96.6% to 113%,with RSDs of less than 5%.Under optimized experimental conditions,a simultaneous determ... |
