本文采用透明胶纸作为X射线荧光光谱分析中粉末样晶的支持物,实现了催化剂中高含量铜和锌的薄样法定量测定。实验表明,在横跨三个数量级的含量范围内,不加内标,用相对强度测定,其制样精度好于5％,分析结果与化学分析结果基本一致,取样量小于2mg.该方法具有简单、快速和成本低的特点,适用于微量样品的分析。 In this paper, the transparent adhesive tape is used as the support for the powder-like crystal in X-ray fluorescence spectrometry, and the quantitative determination of high content copper and zinc in the catalyst is achieved. The experimental results show that the sample preparation accuracy is better than 5% without any internal standard when the content is within three orders of magnitude, and the analysis result is basically consistent with the result of chemical analysis, the sampling amount is less than 2mg. The method has the advantages of Simple, fast and low cost, suitable for the analysis of trace samples.
