摘　　要：本文用HCl+HNO3+H2O2消解处理采集在滤膜(或滤筒)上的悬浮颗粒物(或烟尘)样品,火焰原子吸收光谱法测定试液中的铅、镉,方法快速、简便、结果准确。A new method of determinating Lead and Cadmium in suspended particulates in air and in soot dust is developed. The samples of suspended particulates (or soot dust) collected on filtration membrane (or filtration column) are first dissolved in HCl+HNO_3+H_2O_2 solution, and the Lead or Cadminum content is determinated by atomic absorption spectrometry. This method is quick and easy, and the results are quite accurate.
