| Abstract: | The optimum experimental conditions were studied for the determination of germanium by hydride generation atomic fluorescence spectrometry with orthogonal design , and the results obtained were evaluated. The detection limit was 2. 3ng/ml, relative standard deviation 3. 34% (n=ll), and recovery more
than 97%. The method has been applied to determine germanium in healthy foods. |
