| 中文摘要: |
| 根据交流电弧发射光谱法具有可同时测定多个元素和多条谱线的优势,探讨了利用Sn的灵敏线(317.502 nm)和次灵敏线(285.062 nm)同时测定Sn含量范围跨度较大的样品。对GBZ-Ⅱ型光谱相板测光仪的软件工作条件进行特殊设置,通过灵敏线317.502 nm测定样品中x~xxμg/g的Sn,次灵敏线285.062 nm测定样品中0.0x%~x%的Sn。本方法同时测定两条不同灵敏度的分析谱线,兼顾了交流电弧发射光谱法具有较高灵敏度的优点,拓展了样品的测试范围,避免了传统方法中对高含量样品需进行稀释后再次测定可能带来的污染以及人为引入的误差。 |

| Based on the advantages of simultaneous determination of multiple elements by using different spectral lines of Alternating Current Arc Emission Spectroscopy, samples with a large range of Sn contents were simultaneously determined by the major spectral line of 317.502 nm and the minor spectral line of 285.062 nm. The working condition for the GBZ-Ⅱ spectral phase plate light meter was optimized by improving the software function. The 317.502 nm spectral line was selected to measure x~xx μg/g Sn in the sample, while the spectral line of 285.062 nm was selected for the determination of 0.0x%~x% Sn. The established method can simultaneously detect two spectral lines with different sensitivities. According to the advantage of high sensitivity by the alternating current arc emission spectroscopy, the high Sn content sample can be analyzed without any dilution, which avoids contamination and artificial errors. |
