摘要
研究了用火焰原子吸收分光光度法测定大气飘尘中痕量铅、铜、锰、铁、钙、镁,回收率96%～104%,相对标准偏差在4%以内.六种元素的线性良好,相关系数在0.9997～0.9999之间.
It is reported in this paper that flame atomic absorption spetrometry is used for the determination of trace amounts of Pb Cu Mn Fe Ca and Mg in atomospheric duct. The rate of recovery is 96%-104% and RSD obtained is smaller than 4%. The linear relationship between the concentrations and absorbances for the six aboved mentioned elements are good. The corelative coefficients found are between 0. 9997-0. 9999.
