微量元素分析方法在地质调查植物样品分析中的应用

TRACE ELEMENT ANALYSIS OF PLANT SAMPLE IN GEOLOGICAL INVESTIGATION

针对地质矿产实验室对植物样品分析中存在的主要问题,在总结、论述植物叶片中各种微量元素的分析意义及相应的分析方法的基础上,利用地质样品微量元素的现代分析技术,探讨了地质调查植物样品的处理方法。并利用原子吸收、电感耦合等离子体发射光谱、原子荧光对植物叶片中N、P、As、Hg、K、Cu、Pb、Zn、Co、Ni、Cr、Cd、Mo、Mn14个元素进行了应用检测,利用国家标准物质GBW07603、GBW07604进行了验证,其准确度、分析误差、合格率等技术指标符合质量控制的要求,证明方法行之有效,能适应和满足现代地质调查植物样品分析工作的需要。

In view of the geological minerals laboratory the main question which exists to the plant sample analysis in, in the summary, in the elaboration plant leaf blade each kind of trace element analysis significance and in the corresponding analysis method foundation, the use geology sample trace element modem analysis tech- nology, has discussed the geological investigation plant sample sample preparation method, and using the atomic absorption, the inductive coupling plasma emission spectrum, the atomic fluorescence to the plant leaf blade in N, P, As, Hg, K, Cu, Pb, Zn, Co, Ni, Cr, Cd, Mo, the Mn 14 elements has carried on the application examination, using national standards material GBW07603, GBW07604 has carried on the confirmationlts technical specifica- tions and so on accuracy, analysis error, qualified rate conform to the quality control requirement, proved the method is effective, can adapt and satisfy the modem geological investigation plant sample analysis work the need.
