| Abstract: | A method was established for the determination of cadmium in edible vegetable oil by atomic fluorescence spectrometry using the Microwave Digestion.The good linear relation was determined as 0～2.0ng/mL by atomic fluorescence spectrometry with a regession coefficient of 1.0000.The detection limit was 0.0078 ng/mL and the recovery rate of spiked samples ranged above 90%.This method was simple,rapid and accurate,with high sensitivity,precision and low detection limits.This method was suitable for determination for cadmicim in edible vegetable oil. |
