摘要
采用波长色散X射线荧光光谱仪测定黄铜中铜、铅、铁、铋、锑、磷和砷。考察了试样表面质量对测量结果的影响,并对黄铜中元素间的吸收增强效应进行了研究。实验发现,吸收效应对黄铜的分析结果有较大影响,需用理论α影响系数进行基体效应校正。采用本法分析了多种黄铜标准样品(普通黄铜、加砷黄铜和特殊黄铜),结果显示,普通黄铜和加砷黄铜的分析结果与标称值相符。文中还给出了方法的实验室内和实验室间的精密度试验结果。
Sequential X-ray fluorescence spectrometer has been used to determine copper, lead, iron, bismuth,antimony,phosphorus and arsenic in brass. The influence of sample surface status on analysis results was tested, and the absorbability and enhancement between elements were studied. The theoretical a influence coefficents were used to correct the matrix effects. The results showed that the absorbability had large influence on the determination. The developed method was applied to the analysis of 49 brass standard samples（29 common brass, 20 special brass）, the analysis results were consistent with the certified value. The repeatability and reproducibility of this method were also given in this paper.
