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 matrix effect and its correction. The method has been applied to the determination of Si, K, Ca, Ti, Mn, Fe and Sr in standard soil samples. The results are in agreement with certified values with precision of <3% RSD ( n =5).

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 和Sr 7 种主、次量元素进行测定。讨论了基体效应及校正等问题。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( RSD,n = 5) < 3 % 。

Eight components, i.e. TFe, CaO, MgO, Al_2O_3, SiO_2, TiO_2, MnO and P_2O_5 in refining furnace slag were determined by X ray fluorescence spectrometer. Because the content of CaO was high, the authors selected 12 national and departmental grade slag (standard) samples and prepared a series of synthetic standard samples by adding spectrally pure reagents to them. The calibration curve is suitable to the sample analysis of CaO, MgO and SiO_2 with widely varying range. Meanwhile, the points on the...

Eight components, i.e. TFe, CaO, MgO, Al_2O_3, SiO_2, TiO_2, MnO and P_2O_5 in refining furnace slag were determined by X ray fluorescence spectrometer. Because the content of CaO was high, the authors selected 12 national and departmental grade slag (standard) samples and prepared a series of synthetic standard samples by adding spectrally pure reagents to them. The calibration curve is suitable to the sample analysis of CaO, MgO and SiO_2 with widely varying range. Meanwhile, the points on the curve are even. The samples were prepared at high temperature by adding Li_2B_4O_7 as flux. The experiments for the selection of the sample preparation conditions about strip reagents, melting temperature and dulition ratio were carried out. The matrix effects on absorption and (enhancement) (were) corrected by means of PH model and theoretical alpha coefficient. Moreover, the precision and accuracy experiments were performed. In comparison with chemical analysis method, the quantitative analytical results for each component are satisfactory. The method has proven rapid, precise and simple.
