| Abstract: | The simultaneous determination of trace amount of copper, zinc, lead, cadmium, nickel and chromium in soil was developed by atomic absorption spectrometry (AAS) with digestion under high pressure in a closed pot. Compared with different system of digestion, the optimum digestive and experimental conditions were selected. The recoveries of the trace six kinds of metal in soils ranged from 86% to 110%, and the relative standard deviation was less than 8.0%(n=6). |
