摘要
将WP-1米平面光栅摄谱仪改造成CCD-1型平面光栅电弧全谱直读光谱仪,在原有CCD-1平面光栅电弧直读发射光谱仪测定硼、锡、银、钼基础上,建立了一次摄谱同时测定化探样品中铅、锡、钼、铜、银、锌6种元素的分析方法。实验表明,6种元素测定的检出限分别为Pb 1.56、Sn 0.42、Mo 0.21、Cu 0.87、Ag 0.012、Zn 7.95μg/g,相对标准偏差(RSD,n=12)为1.3%～7.4%,方法的准确度、精密度都能满足地质矿产实验室管理的要求。
On the basis of the determination of B,Sn,Ag and Mo by the original CCD-1 plane grating electric arc direct reading emission spectrometer,the analytic method that six elements Pb,Sn,Mo,Cu,Ag,Zn can simultaneously be determined on a single run was developed by transforming the original WP-1 plane grating spectrograph into CCD-1 plane grating electric arc direct reading emission spectrometer.The detection limit of six elements was Pb 1.56,Sn 0.42,Mo 0.21,Cu 0.87,Ag 0.012,Zn 7.95μg/g,and relative standard deviation(RSD,n=12)between 1.3%to 7.4%.The results show that the accuracy,the precision,the detection limit and the qualification rates can meet the requirements of the geological and mineral laboratory management regulations.
