| Abstract: | A method has been studied for the determination of cadmium in grain by graphite furnace atomic absorption spectrometry. The best condition of the instrument has been selected, the detection limit, precision and the rate of recovery have been studied. The detection limit is 0.93 pg, the rate of recovery is 100.2 % - 105.9 %, RSD is 1. 4 %. This method features high sensitivity and accuracy, low detection limit as well as simple and rapid operation. |
