Abstract
The contents of Cd in soil in Zeeman effect, (NH_(4))_(2)HPO_(4) is as matrix modifier, are determined by graphite furnace atomic absorption spectrometry. The method detection limit is 0.012μg/g, precision (RSD, n=12) is 3.55%~7.33%. It can satisfy quality request for determining cadmium in soil samples.
