【摘要】 应用 ICP- MS测定了海南中部山区野生枫香中稀土元素的含量 ,讨论了其分布区间尺度 ,稀土元素总含量中占有最大比值的是 Ce,为 33.14% ,其次是 L a、Nd。绘制了含量区间谱图。枫香中稀土元素的含量区间位于 4.5～ 7.0 μg/ g之间 ,波形平缓 ,波幅小 ,可推断其为辛味药性更多还原

【Abstract】 We have determined the contents of 13 rare earth elements(REEs) by ICP-MS in the leaves stems of wild liquidambar formosana which grows in the mountain areas of central Hainan Island.We have founded that in REEs contents ratio of Ce highest,33.14%,next La,Nd.Because REEs area is between 4.5~7.0,it is refered to the Xin taste from the level of the contents of REEs.更多还原
