| 摘 要： | 根据植物示踪地球化学找矿理论， 建立植物中稀土元素的分析方法， 为植物示踪地球化学找矿寻求快捷可靠的新手段. 采用高温灰化植物样本， 氢氟酸-盐酸-硝酸-硫酸一次溶解植物灰分， 电感耦合等离子体质谱法（ICP-MS）同时测定15种稀土元素. ICP-MS法可以减少化学分离富集的复杂操作程序引进的
误差， 操作简便， 检测快速， 以国家标准物质GBW07603检验方法的准确度， 结果与标准 值相符， 该方法的准确度用相对误差衡量在3.00%~14.10%之间， 精密度（RSD， n=8）在3.22%～20.00%之间.

| Abstract: | On the basis of the theory of plant trace geochemistry prospect mine an analytic method of rare elements in plant is established, providing a rapid credible new means for
plant was ashed by the method of high temperature furnace bake over a weak flame. The hydrof luoric acid-hydrochloric acid-nitric acid-vitriol (HF-HCl-HNO3-H 2SO4) system was used for the determination of 15 rare earthelements in the ash of plant by inductively coupled plasma mass spectroscopy (ICP-MS). The method of inductively coupled plasma mass spectroscopy can reduce the error introduced by chemistry separate and enrichment complex operating process, the operation is simple and the examine is quickly. The result of method is in agreement with the standard of nationality standard substance GBW07603.
The experiment method measurement accuracy is 3.00%～14.10% in relative error, t heprecision(relatively standard deviation, number=8) is in the range of 3.22%~20.00%. |
