| Abstract: | Germanium was successfully determined by FIA-HG-GFAAS with matrix modifiers Pd and Pd-Mg.The sensitivity,precision and analysis efficiency have been improved,The characteristic mass at the peak height absorption is 8.0 pg,the detection limit is 10.9 pg and the relative standard deviatiation is 0.34%.The stabilization mechanism of the matrix modifier Pd and the atomization mechanism of germanium hydride in the graphite furnace were discussed. |
