摘要
采用粉末样品压片制样，土壤标准物质以及人工合成标样为标准，用Ｘ 射线荧光能谱仪对土壤试样中的Ｓｉ、Ｋ、Ｃａ 、Ｔｉ、Ｍｎ 、Ｆｅ 和Ｓｒ ７ 种主、次量元素进行测定。讨论了基体效应及校正等问题。方法经土壤标样分析验证，其结果与标准值符合较好，方法的精密度（ ＲＳＤ，ｎ ＝ ５） ＜ ３ ％ 。
A method for the determination of major and minor elements in soils by X ray energy spectrometry with pressed powder pellet sample preparation method was developed. Standard reference soil samples and synthetic standard samples were used to study the matrix effect and its correction. The method has been applied to the determination of Si, K, Ca, Ti, Mn, Fe and Sr in standard soil samples. The results are in agreement with certified values with precision of <3% RSD ( n =5).
