| Abstract: | A method is reported for determination of trace plumbun in food by hydride generation atomic fluorescence spectrometry in this paper. The effect of medium and amount of acid and reduction agent on determination of Pb are investigated. The operation condition of hydride generation is optimized. The interference from element formed hydride compound and coexistent element in food and the digestion method are studied, too. By the recovery and accuracy testing, the method is simple, accurate and quick. It has been applied to the determination of Pb in import-export food. |
