摘要: 采用岛津MXF-2400型多道X荧光光谱仪测定锌铝硅合金中硅及铁的含量,对样品分析面进行了选择,考察了分析面光洁度、样品放置时间对测定的影响条件.方法样品前期处理简便,分析速度快,灵敏度高,硅和铁的相对标准偏差(RSD,n=11)分别为1.15%和0.44%.与其他方法对照,结果相符.Abstract: SHIMADZU MXF 2400 Multi-channel X-ray fluorescence spectrometer was used in the determination of silicon and iron in zincaluminumsilicon alloy. The effect of determination conditions including the sample surface smoothness and sample detection time on the determination results was studied. Under the optimized determination condition, the proposed method has been applied to the determination of silicon and iron in zincaluminumsilicon alloy. The results are in agreement with those by other methods with precision (RSD, n=11) of 1.15% for silicon and 0.44% for iron. The method provides the advantages of simple sample pretreatment, high sensitivity and high sample throughput.
