摘　　要：建立用火焰原子吸收法快速测定尘土中铜含量的分析方法.硝酸和盐酸体系进行湿法消解,然后采用火焰原子吸收光谱法测定铜的含量.此方法平均回收率在98.9%~107.0%范围内,用标准物质测定的相对标准偏差(RSD)的范围为2.05%~3.21%.此方法具有操作简单,快速方便及自动化程度高等优点,且实验结果令人满意.To establish method, the content of copper in the dust was analyzed by flame atomic absorption spectrome-try.To detect the content of copper with wet digestion by Nitric acid-Hydrochloric acid system, and then analyze the atomic absorption spectrometry . The recoveries are between 98.90%~107.0%, and the relative standard deviation (RSD)of the Standard material is 2.05%~3.21%.The results show that the method is simple, fast and easy and the advantages of automation, and the result is satisfactory.
