摘　　要：本文采用微波消解法对大气颗粒物进行预处理,通过火焰原子吸收光谱法测定大气颗粒物中重金属铜、镉的含量。微波消解-火焰原子吸收法测定简便,成本低。研究发现,空气中的颗粒物浓度和铜浓度随天气变化而变化,下雨前浓度较高,而镉含量随天气变化不明显。In this paper,microwave digestion method is used to pre-treat atmospheric particles,and the content of heavy metals copper and cadmium in atmospheric particles is determined by flame atomic absorption spectrometry.The microwave digestion-flame atomic absorption method is simple and low-cost.The study found that the concentration of particulate matter in the air and the concentration of copper change with the weather,the concentration is higher before rain,while the cadmium content does not change significantly with the weather.
