X射线能地测定土壤中7种主次量元素

Determination of Major and Minor Elements in Soils by X-ray Energy Spectrometry

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、Ｓｒ７种、次量元素进行测定。讨论了基体疚及校正等问题。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《３％

Abstract: 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 m
