摘要
采用粉末压片制样-X射线荧光光谱法研究地质样品中硫(S)和氟(F)元素的快速测定方法。通过分级过筛实验优化确定样品粒度,探讨样品粒度对测定结果的影响,并进行实际样品和标准物质验证。结果显示,样品粒度为85μm时,经实际样品和标准物质验证,测定结果与化学值和标准认定值相符,且相对标准偏差(RSD)均小于2%。方法具有准确度高、检出限好、测试范围宽、简便快速等优点,能确保样品分析结果的准确性,实现了地质样品中S和F的快速测定。
The rapid determination method of sulphur and fluorine in geological samples by X-ray fluorescence spectrometry with pressed powder preparation was studied. The particle size of the sample was optimized by the sieving experiment, and the effect of the sample particle size on the determination results was discussed. The results show that verified by actual samples and standard substances, the measured results were consistent with the chemical values and the standard values, and the relative standard deviation (RSD) was less than 2%, when the sample size was 85 μm. The method has the advantages of high accuracy, good detection limit, wide test range, simple and rapid, etc., which can ensure the accuracy of sample analysis results and realize the rapid determination of S and F in geological samples.
