[A Zeeman graphite furnace atomic absorption spectrometric method for the determination of trace copper and chromium in drinking water].

The determination of trace copper and chromium in drinking water is described in this paper using transverse heated graphite atomizer (THGA) with the technique of Zeeman effect background correction without any other matrix modifiers. The method is fast, and simple with low detection limit which makes it possible to be used for routine analysis of drinking water.
