本文叙述了用波长色散X射线荧光光谱测定环境土壤样品中Pb、Zr、Sr、Rb、Zn、Cu、Ni、Fe、Mn、Ti元素的条件。用GSD参考标样建立的元素含量与X射线强度间的函数式线性良好,方法的可靠性用GSD参考标样检验,各元素测定结果的相对标准偏差均在4.85%以下。文中还讨论了用非线性方法研究样品稀释比与X射线强度间的线性关系,同一样品中各元素稀释比与X射线强度间的非线性关系,可用线性的经验方程表示。 This paper describes the determination of Pb, Zr, Sr, Rb, Zn, Cu, Ni, Fe, Mn and Ti in soil samples by wavelength dispersive X-ray fluorescence spectrometry. The linear correlation between elemental content and X-ray intensity established by GSD reference standard was good. The reliability of the method was tested by GSD reference standard. The relative standard deviations of the determination results of each element were all below 4.85%. The paper also discusses the non-linear method to study the linear relationship between the sample dilution ratio and the X-ray intensity. The nonlinear relationship between the element dilution ratio and the X-ray intensity in the same sample can be expressed by a linear empirical equation.
