摘　　要：为实现快速、准确地测定电炉渣组成成分含量,应用X射线荧光光谱法测定电炉渣中铜、铁、硫、硅、钙、镁、铝、砷、铅、锌、锑、铋、镍等元素。探讨了测定电炉渣样品分析过程中的样品制备、仪器条件设定、标准样品选择、标准曲线制作和标准曲线校正等关键参数过程控制。按照试验方法选择10个电炉渣样品进行分析测试,结果显示:13个分析元素重复性标准偏差在0.001%~0.106%之间,再现性标准差在0.003~0.186之间,以Cu、Fe、S、SiO2为主要考察元素与化学法比对最大绝对误差1.1%,最小绝对误差0.040%。In response to fast and accurate measurements of the composition and content of elements(copper,iron,sulfur,silicon,calcium,magnesium,aluminum,arsenic,lead,zinc,antimony,bismuth,nickel,and so on)in electric furnace slag,X-ray fluorescent spectrometry method is adopted.This paper explored the sample preparation,instrument condition setting,standard sample selection,standard curve fabrication and standard curve correction,and the other critical parameters and process control of electric furnace slag samples.According to the test method,selecting 10 electric furnace slag samples for the analysis test,results show:that the element repeatability limits standard deviation of 13 analysis elements is in the range of 0.001%~0.106%,the reproducibility limits standard deviation is in the range of 0.003~0.186,taking Cu,Fe,S,SiO2 as the major investigated element,the maximum absolute error compared with the chemical method is 1.1%,the minimum absolute error is 0.040%.
