| 摘 要： | 采用一定规格的石墨探针可直接收集大气微料物质（ＡＰＭ）。然后，立即采用石墨探针炉原子吸收光谱测定收集在探针上的ＡＰＭ中痕量铜。方法简便，快速。在０－５５０ｎｇ／ｍＬ范围内，铜的浓度与峰面积吸光度呈良好的线性关系。铜的特征量为２２．０ｐｇ，检出限为６．６ｎｇ／ｍＬ。分析标准参比材料，铜的回收率达９８％，相对标准偏差为３．３％。

| Abstract: | Direct determination of trace copper in atmospheric par-ticulate matter was done by graphite probe furnace atomic absorption spectrometry after collection with a graphite probe filter. The new method was simple and rapid. The concentration of copper and ahsorbance (peak-area mode) showed excellent linear relation in the range of 0- 550 ng/ml. The characteristic mass and detection limit of copper were 22. Ong and 6. 6ng/ml, respectively. The results of analysis of the National Bureau of Standard (NBS), Standard Reference Material (SRM) No. 1648, urban paniculate matter, gave recovery of 98% and a precision of 3. 3% RSD. |
