| Abstract: | The analytical method for the determination of the content of lead in milchigs was established by flow injection-hydride generation-atomic fluorescence spectrometry(HG-AFS).The conditions of instrument and reaction were choosed and optimized.The detection limit of the method was 0.30μg/L and the RSD was less than 4.7%,and the recoveries were in the range of 90.0%—114.5%,and that met the analytical requirements of trace elements in foods. |
