摘要:
目的:探讨山楂中有害金属元素砷(As)、铬(Cr)、铅(Pb)的含量测定方法。方法:运用能量色散X射线荧光光谱(EDXRF)法测定山楂中的有害金属元素As、Cr、Pb的含量,并从样品颗粒粒径、紧实度、含水量等方面对测量条件进行选择。结果:筛选得到的EDXRF最佳测量条件为:颗粒粒径200目,紧实度30 Mpa,压片30秒,含水量<5%。将该条件下的测量结果与电感耦合等离子体原子发射光谱法(ICP-AES)对比,结果准确,可信。结论:EDXRF法测定准确,适用于大量中药金属元素的快速测定。
Abstract:
Objective: To discuss the determination methods for the contents of harmful metal elements As, Cr and Pb in hawthorn. Methods: The contents of As, Cr and Pb in hawthorn were detected by energy-dispersive X-ray fluorescence (EDXRF), the detection conditions were chosen in the light of the size of particle, the degrees of ramming, moisture content and othes of the samples. Results: The optimal detection conditions of EDXRF were: particle size 200meshes; the degrees of ramming 30 Mpa; tablet compressing for 30 s and moisture content<5%. The results detected under the conditions were compared with ICP-AES, the results were accurate and reliable. Conclusion: The method of EDXRF is accurate and suitable for rapid determination of the elements in the herbs
