| 摘 要： | 本文研究了以粉末样品直接压片,铑靶X光管的康普顿散射线作内标和背景的扣除,测定地质样品中微量铌、锆、钇、铷、锶、铀、铜和锌等元素的X射线光谱分析方法。本法具有制备样品简便快速、扣除背景简易准确以及能较好地克服基体效应、方法检测限较低(<2ppm)等优点。方法的精密度与准确度符合分析误差要求。因而本法是测定岩石样品中微量元素的一种简便快速且又较为准确的分析方法。

| Abstract: | This paper describes a XRF method for determination of trace elements Nb, Zr, Y, Rb, Sr, U, Cu and Zn in rock samples using pressed rock powder pellets. The compton scatherinS of Rh X-Ray tube is used as matrix correction and background abstract. The method has following abvantages: pressed pellets preparation are simple and rapid; background abstract and matrix correction are easy and accurate; Detection limits for these trace elements are less than 2 ppm, so that, this method offers the possibility of rapid and accurate for determination trace elements in rock materials. |
