The paper presents results for the speciation analysis of lead in dusts derived from dedusting of technological gasses from metallurgical processes of non-ferrous metals with different elementary content, made in accordance with two equal sequential extractions. Analytical procedure A provided possibilities for determination of fraction of Pb(2+), metallic lead and fraction containing mainly lead sulfides. The second procedure (procedure B) was sequential extraction in accordance with Tessier. The results obtained in accordance with procedure A indicate that, regardless of the dust origin, the dominant group of Pb compounds is composed of lead salts which are soluble under alkaline conditions or lead compounds that form plumbites in the reaction with NaOH.
本文介绍了对有色金属冶金工艺中不同元素含量的工艺气体除尘产生的粉尘中铅的形态分析结果，该分析按照两种相同的连续萃取方法进行。分析程序A提供了测定Pb(2+)、金属铅以及主要含硫化铅部分的含量的可能性。第二种程序（程序B）是按照 Tessier 方法进行的连续萃取。根据程序A获得的结果表明，无论粉尘来源如何，铅化合物的主要类别是在碱性条件下可溶的铅盐或在与NaOH反应中形成亚铅酸盐的铅化合物。
