| Abstract: | Geological samples dissolved by aqua regia and extracted by MIBK.The operation condition for the instrument was optimized.Trace cadmium in geological sample was determined by graphite furnace atomic absorption spectrometry.The precision RSD≤5.6%(n=6).The detection limit of the method is 0.04μg/g(the injection volume is 10μL).The method has been applied to the determination of cadmium in country standard reference rock samples and the results are in agreement with certified values. |
