摘要
选用不同种类的一组块状钢铁标样，采用燃烧曲线法确定最佳分析参数，用ＢＡＩＲＤＳＰＥＣＴＲＯＶＡＣ２０００ＣＤＶ－５，ＨＲ－４００光源，光电直读光谱仪测定钢材中Ｐ，Ｓ，Ｐｂ，Ｃｕ和Ａｓ五种有害杂质元素。该方法可用一组标样分析多种钢样，方法简便实用。分析结果相对标准偏差（ＲＳＤ）小于１０％，基本与标准值一致。
The P,S,Pb,Cu and As five pernicious elements in steel weredetermined by model BAIRD SPECTROVAC 2000 CDV-5, HR-400 light source,photoelectric direct reading spectroscopy,and with burn--off curve method,the optimum analytical parameters were determined from a group of different lump steelreference samples. The result showed that its relative standard deviation(RSD) wasless than 10%,basically in agreement with certified values. This method is simpleand practical,which can analyse various steel samples by a group of reference samples.
