X射线荧光光谱压片法测定六种花瓣粉末的成分

利用X射线荧光光谱法对白玫瑰花、红玫瑰花，白康乃馨、红康乃馨，白蝴蝶兰、红蝴蝶兰3个品种6个粉末样品中元素的种类和含量进行测定，并就每组样品的测定结果进行分析比对。结果表明，3个品种的花瓣粉末中均未检测出有毒元素的存在，且花瓣粉末中元素含量丰富;除含有常量元素外，还含有如Fe，Cu，Zn，Mn，Ni，Si，Sr，Rb等多种微量元素，但3个品种的微量元素的种类及含量有所差异;同一品种的花瓣粉末中元素的种类大致相同，而元素含量却各有差异，白色比红色中元素含量高。

The Element Determination of Six Samples of Petal Powders by Using XRF Spectrometry

Elements and contents in three kinds of petal powders of white and red rose, carnation, and butterfly orchis were determined by using XRF technic, and the data for every group were compared and analysed. The results indicated that all powders contain no toxic elements determined but have lots of normal elements and trace elements, such as Fe, Cu, Zn, Mn, Ni, Si, Sr, and Rb. The same sort of powder had approximately equivalent elements but their contents are different, and the element content of the white sort. was higher than the red one.
