摘要
采用火焰原子吸收法同时测定了洋槐花中K,Na,Ca,Mg,Pb,Cd,Cu,Mn,Co,Zn,Cr,Fe等12种微量元素的含量.方法的相对标准偏差介于0.07%～2.31%,回收率介于97.0%～107.0%.结果表明,洋槐花中含有丰富的微量元素,其含量K＞Ca＞Mg＞Na＞Fe＞Zn＞Cu＞Mn＞Co＞Pb＞Cr＞Cd,说明洋槐花具有较高的营养价值.
The twelve trace elements in the pagoda flower, including K, Na, Ca, Mg, Pb, Cd, Cu, Mn, Co, Zn, Cr and Fe were determined simultaneously by FAAS. The relative standard deviation of the method is 0.07 %-2.31%, and the recovery is 97.0 %- 107.0 %. The analytical results were satisfactory. The results showed that there were comparatively rich metal elements in the pagoda flower. Proportions of the twelve elements are in the order that K 〉 Ca 〉 Mg 〉 Na 〉 Fe 〉 Zn 〉 Cu 〉 Mn 〉 Co 〉 Pb 〉 Cr 〉 Cd. It implied that the nutritive value of the pagoda flower is high.
