| Abstract: | A method for determination of trace Germanium in edible fungus by atomic fluorescence spectrometry using hydride generation with alkaline mode was described. The influences of HG-AFS operating parameters and hydride generation conditions on the fluorescence intensity of Ge were investigated. The interference of 20 co-elements were studied.The trace germanium in edible fungus was determined under the optimized conditions.The interference was eliminated effectively. The detection limit of the method is 0.76 μg/L (3σ) with relative standard deviation of 0.81% and recovery of 94.6～101.3%. |
