X射线荧光光谱法测定土壤中26种主次元素和微量元素

DETERMINATION OF 26 MAJOR, MINOR AND TRACE ELEMENTS IN SOIL BY X-RAY FLUORESCENCE SPECTROMETRIC METHOD

采用粉末压片制样技术和X射线荧光光谱法 ,测定了土壤中 2 6种元素。将经验系数法与康普顿散射线内标法相结合 ,校正了元素间的基体效应。方法的精密度 (RSD)为 0 5 %～ 10 %

The 26 major, minor and trace elements existing in soil are determined by X ray fluoresence spectrometric method with pressed powder pellet sample preparation. The inter element effect is corrected by using empirical coefficient method combined with scatter line as internal standard. The precision (RSD) is 0.5 %～10 %?
