石墨炉原子吸收法连续测定沱江河水中的Cu、Pb、Cd、Cr

Continuous Determination of Cu,Pb,Cd,Cr in Tuojiang River by Graphite Furnace Atomic Absorption Spectrometry

采用热解涂层石墨管 ,应用氘灯扣除背景技术 ,在无任何基体改进剂的条件下 ,提出连续测定沱江河水中 Cu、Pb、Cd、Cr的方法。该方法操作简便、检出限低 ,快速、准确 。

The continuous determination of copper,lead,cadmium,chromium in Tuojiang river is described in this paper by using pyrolytic coating graphite tube under the technique of BGC D2 background correction without any other matrix modifiers.The method is simple,fast and accurate,with low detection limit which makes it possible to be used for metal element analysis of Tuojiang river.
