| 摘 要： | 建立了离子体发射光谱仪测定钢中铈元素的方法。为消除共存元素对铈分析游线的光谱干扰，选择Ce413．380nm作为分析线，铈含量在0．005％-0．50％之间工作曲线线性良好。对于含量范围在0．005％-0．10％的铈元素，回收率为85．6％-12．5％，测定结果的相对标准偏差小于9．74％（n=8）；对于含量范围在0．10％-0．50％的铈元素，回收率为99．5％-103．0％，测定结果的相对标准偏差小于3．52％（n=8）。该方法适宜钢中含量范围在O．005％-0．50％的铈元素的测定。

| Abstract: | The method for determining Ce in steel by ICP–AES was established.Ce 413.380 nm was selected as the analysis wavelength to eliminate the spectral interference of coexist elements in steel.The working curve had a good linear relationship with Ce content in the range of 0.005%–0.50%.The recoveries were 85.6%–112.5%,RSD was less than 9.74%(n=8) in the range of 0.005%–0.10% for Ce,and the recoveries were 99.5%–103.0%,RSD was less than 3.52%(n=8) in the range of 0.10% – 0.50% for Ce.The method is suitable for determining Ce in steel with the content of 0.005%–0.50%. |
