火焰原子吸收测定锆和铪需要用高温一氧化二氮-乙炔富燃火焰。Amos和Willis,Bond等人及Sastri等人研究过锆和铪的火焰原子吸收测定,发现氟化物、三价铁、含氮化合物有增感效应,并利用这种效应拟定了间接测定氟离子和氨的方法。Panday较系统地考察过各种共存元素对锆、铪、钛的原子吸收测定的干扰。本文在上述工作的基础上,探讨大量铪或者锆存在下,火焰原子吸收测定少量锆或铪的可能性。
Flame atomic absorption determination of zirconium and hafnium requires high temperature nitrous oxide - acetylene rich combustion flame. Amos and Willis, Bond et al., And Sastri et al., Studied the flame atomic absorption spectrometry of zirconium and hafnium and found that the fluoride, ferric, and nitrogen containing compounds have sensitizing effects and the indirect effect of fluoride ion and Ammonia method. Panday systematically investigated the interference of various coexisting elements on the atomic absorption spectrometry of zirconium, hafnium and titanium. Based on the above work, this paper discusses the possibility of a small amount of zirconium or hafnium with flame atomic absorption spectrometry in the presence of a large amount of hafnium or zirconium.
