快速确定碳钢及铸铁中铅、锑的含量是科研工作者所关心的问题。Burke等人采用的火焰原子吸收分析法需经萃取分离富集,手续冗长;Plotnikova虽然采用石墨炉法测定,但试样的处理仍未避免萃取与反萃取;Norman及史再新等在用石墨炉法测定时采用了氘灯校正背景法。而利用塞曼效应测定铁基材料中铅锑,国内未见报道。我们用塞曼无火焰原子吸收法直接测定铸铁中痕量铅锑的试验,建立了快速测定铁基材料中痕量铅锑的方法。
Rapid determination of carbon steel and iron in the lead, antimony content is the concern of scientific researchers. Flake atomic absorption spectrometry used by Burke et al. Is subject to extractive separation and enrichment with lengthy procedures; Plotnikova, although measured by the graphite furnace method, has not yet been subjected to extraction and stripping; Norman et al. Furnace deuterium lamp was used to determine the background correction method. However, the use of Zeeman effect determination of lead-antimony in iron-based materials has not been reported in China. We used the Zeeman flameless atomic absorption spectrophotometry method for the direct determination of trace amounts of lead and antimony in cast iron and established a rapid method for the determination of trace amounts of lead and antimony in iron-based materials.
