摘要
采用火花源发射光谱仪对钢中的“五害”元素进行了分析和研究。选择了最佳分析条件 ,用曲线回归方法消除Mn ,Ni,Cr和W的干扰。As ,Sb ,Sn ,Bi,Pb的相对标准偏差分别为 2 80 % ,3 18% ,3 5 5 % ,5 13 % ,4 2 0 %。标样中 5元素的分析结果与标准值基本吻合。精度和准确度均满足邯钢冶炼一些品种钢的生产工艺要求。
Five harmful elements arsenic,antimony,tin,bismuth and lead in steel have been analyzed and studied by spark source spectrometry. The optimal conditions of determination are selected The interferences by manganese,nickel,chromium and tungsten can be overcome by regression of curve The RSD are 2 80% for arsenic,3 18% for antimony, 3 55%for tin,5 13% for bismuth, 4 20% for lead The analytical results of five elements in certified reference materials are corresponding with certified values The precision and accuracy can meet a demand for production craft of some variety steels manufactured by Handon iron and steel group co .
