| 摘 要： | 利用新型的ZSX Primus Ⅱ型X射线荧光光谱仪采用粉末压片法直接测定土壤样品中的C、N、S、Cl等31种元素。各元素分析晶体为N采用RX45，C采用RX61，Na、Mg采用RX25，C1、S、P采用Ge，Si、Al采用PET，其余元素均采用LiF200。结果表明，方法的检出限、精密度和准确度对绝大多数元素而言，均可满足多目标地球化学调查样品分析的质量要求：

| Abstract: | A method for the determination of 31 components including C, N, S, Cl in soil samples by X-ray fluorescence spectrometry with pressed powder pellet sample preparation was developed. The analytical crystals were carefully selected with RX 45 for N, RX 61 for C, RX 25 for Mg, Na, Ge crystal for Cl, S and P, PET for Si and Al, LiF 200 for other elements. The detection limits, precision and accuracy of the method for most elements can meet the requirements of sample analysis in multi-objective geochemical survey. |
