摘 要：<正> Various experimental conditions were described for the vanadium determination by graphite furnace atomic absorption spectroscopy (GFAAS). The experiments showed that when atomization took place under the conditions where the combination of a pyrolytic coating graphite tube and fast raising temperature were used and the temperature was stable, the signal peak shapes could be improved, the sensitivity was enhanced, and the memory effect was removed. The vanadium in food and traditional Chinese medicinal herbs can be accurately determined using the standard curve method.
