摘要
目的:采用微波消解法处理蒙药蓝盆花样品,电感耦合等离子体原子发射光谱ICP-AES法测定其中Al,As,B,Ba,Cd,Co,Cu,Fe,Hg,In,Mn,Pb,Sr,Zn等14种微量元素的含量。方法:选择ICP仪器最佳测定条件为射频功率1.15 kW,载气流量1.2 L·min-1,冷却气流量15 L·min-1,辅助气流量0.5 L·min-1,积分时间30 s。结果:该方法检出限为0.000 2～0.006mg·L-1,回收率96.6%～110.6%,RSD<4.29%。结论:此法简便、快速、灵敏度高、准确性好,可对多种元素同时测定。
Objective：The samples of Mongolian medicinal plants of Scabiosa were analyzed by microwave digestion-inductively coupled plasma-atomic emission spectrometry（ICP-AES） for content of many trace elements including Al,As,B,Ba,Cd,Co,Cu,Fe,Hg,In,Mn,Pb,Sr and Zn.Method：A mixture of nitric acid and hydrogen peroxide was used for microwave digestion of samples.Result：The method exhibited a spike recovery range of 96.6% to 110.6%,with RSDs of less than 4.29%.Under optimized experimental conditions,a simultaneous determination of various trace elements was achieved without any interference among them Conclusion：The findings will provide useful evidences for the better exploration and utilization of Mongolian medicinal plants of Scabiosa.
