电感耦合等离子体光谱法测定天山花揪中的微量元素
Determination of the contents of trace elements in Sorbus tianschanica ruper by ICP—AES
【摘要】 目的:建立一种用电感耦合等离子体光谱法测定天山花楸中微量元素及含量的方法。方法:用硝酸—高氯酸进行消解,电感耦合等离子体原子发射光谱法(ICP—AES)同时测定天山花楸样品中B、Ba、Cu、Sr、Ti、Zn、Mn、P、V、Ni、Mg、Ca、Co、C、Al、Fe等多种微量元素。结果:其相对标准偏差为0.73%~2.2%,回收率为93.7%~101.9%。研究表明天山花楸中含有比较丰富的镁元素,微量元素在植物药中可能起到一定的药理作用。结论:ICP—AES法测定简单,快速,灵敏度高,准确度高,且多元素同时测定,适用于天山花楸中微量元素的测定。
【Abstract】 Objective: To develop a method of detecting the trace elements in sorbus tianschanica ruper.ethods: A method of determination of trace elements in sorbus tianschanica ruper was developed by using ICP—AES together with HNO3—HClO4 digestion.Results:The average recovery was 93.7%~101.9% and the RSD of 0.73%~2.2%.The method was applied to the analysis of some practical samples.Relatively abundant Mg was detected.Because the trace elements play an important medical role in plant medicine,Conclusion:the determination of those substances by using ICP—AES is of importance in the assessment of plant medicine.
