本文采用聚芳砜滤筒取样,以盐酸、硝酸简捷溶解铅尘,用原子吸收光谱快速测定了烟道气中的铅,为工业分析和环境保护提供了新方法。本文还用电子显微镜观察了铅烟颗粒大小,并用x射线粉末衍射法测定了铅尘的形态,提出了用重油作燃料熔炼彩色显象管玻璃时从烟道放空的铅尘为硫酸铅,为除尘脱铅提供了依据。 In this paper, polyphenylene sulfone cartridge was used to sample, lead chloride was dissolved in hydrochloric acid and nitric acid, Pb in flue gas was rapidly determined by atomic absorption spectrometry, which provided a new method for industrial analysis and environmental protection. In this paper, the particle size of lead smoke was also observed by electron microscope. The shape of lead dust was determined by X-ray powder diffractometry. The lead dust which was vented from the flue when the heavy oil was used as fuel for smelting the color picture tube was lead sulfate. Dust removal lead provided the basis.
