火焰原子吸收光谱法测定卷烟用纸中Pb和Cu

Determination of Lead and Copper in the Cigarette Paper by Atomic Absorption Spectrometry

卷烟滤嘴棒用的纸样品经硝酸、高氯酸湿法消化,在乙炔-空气火焰下,于波长283.3、324.8nm处,用原子吸收光谱法测定铅和铜的百分含量。方法简便、快速,结果准确。

The lead and copper in sample of cigarette paper were dissolved in HNO3 and HClO4, then the lead and copper in the sample can be determined by acetylene-air-atomic absorption spectrometry at λ=283. 3,324. 8nm. The equipment is HITACHI Z-8200. The method is simple, rapid, convenient and accurate.
