研究健康人群中的发铅水平,不仅有利于早期诊断职业性铅中毒,而且能从中了解到当地环境金属污染的状况。为了普查发铅水平和快速检验调味品中铅的含量,研究一种简便的测定铅的方法,仍有实用意义。由于空气—乙炔焰原子吸收法测定铅的特征浓度一般为0.5ppm,不太适合于人发和调味品中铅的简便测定。因此,石墨炉和气相氢化物原子化法常被应用于测定痕量铅。但前者不易普及,后者需要专用的氢化物发生装置,也不方便。本文采用了新近提
Studying lead levels in healthy people is not only helpful for early diagnosis of occupational lead poisoning, but also for understanding the status of metal contamination in the local environment. In order to censor hair lead levels and quickly test the content of lead in condiments, it is still of practical interest to study a simple method for the determination of lead. As air - acetylene flame atomic absorption method for the determination of the characteristic concentration of lead is generally 0.5ppm, not suitable for the determination of lead in human hair and condiments easily. Therefore, graphite furnace and vapor phase hydride atomization is often applied to the determination of trace lead. However, the former is not easy to popularize, and the latter requires a dedicated hydride generation device, which is inconvenient. This article uses the recent mention
