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
