摘　　要：本文以核孔膜作采样滤膜,HNO_3-H_2O_2浸洗,无焰原子吸收光谱法同时测定大气飘尘中的锰和铅。采样量小,方法简便、快速、准确、灵敏度高,能同时满足大气污染环境中长时和短时监测的需要。A method has been developed for the simultaneous determination of manganese and lead in airborne particles. Nuclepore is used as membrane filters for the collection of airborne particles. The collected samples are digested by nitric acid-hydrogen peroxide solution and then determine by flameless atomic absorption spectrometry. The method has the advantages of small samples, high sensitivity and good accuracy, it can satisfyed the long-time or short-term monitoring of atmospheric pollution.
