X射线荧光光谱法测定黑龙江省有机碳含量较高样品中的硅、铝、铁等元素

通过事先对有机碳含量较高的样品进行高温灼烧,计算其烧失量,再将灼烧后的样品经专用熔剂熔融制样后,经X射线荧光光谱仪测定,能够有效地去除因有机质含量高导致的分析结果的偏差,而且较湿法化学分析节省时间。实验结果表明,该方法的分析结果与湿法化学分析结果偏差很小,准确度较直接压片分析有了大幅提高。

X-ray Fluorescence Spectrometry is Used to Determined Si, Al, Fe and Other Elements in High Corg. Samples Collected from Heilongjiang Province

By burning the sample with a high Corg. at high temperature in advance to calculate the loss on ignition, and then melting the burned sample with a special solvent to prepare the sample and measuring it with X-ray fluorescence spectrometer, it can remove the analysis results deviations caused by high organic matter content effectively, and it can save time compared to wet chemical analysis. The experimental result shows that the analysis results of this method deviate from the results of wet chemical analysis very little, and the accuracy is improved greatly compared with the direct tablet analysis.
