本文介绍了在氢化物原子吸收法中用硫脲和邻菲罗啉作掩蔽剂,消除铁、铬、镍和钴等元素的干扰,并应用于铁镍基、镍基高温合金和金属镍中锑的测定,使用N_2/H_2火焰原子化器。方法灵敏度为0.009微克/1%吸收,锑量在0～0.4微克范围与吸收呈线性关系。本法可测试样中0.000X%的锑,对几种样品进行分析,测得结果与其它方法结果符合。
This article describes the use of thiourea and o-phenanthroline as masking agents in hydride generation atomic absorption spectrometry to eliminate the interference of iron, chromium, nickel and cobalt and other elements, and applied to iron-nickel-base, nickel-based superalloy and nickel metal Determination of antimony, the use of N_2 / H_2 flame atomizer. The sensitivity of the method was 0.009 micrograms / 1% absorption, and the quantity of antimony was in the range of 0 ~ 0.4 micrograms and the absorption was linear. This method can test the sample 0.000X% antimony, several samples were analyzed, the measured results in line with the results of other methods.
