| Abstract: | Relatively low cobalt content of wheat samples were determined by Microwave digestion-graphite furnace atomic absorption spectrometry detection method.This method was simple and fast.It had good accuracy and precision.The operating condition in precess and specimen pretreatment method were discussed.The linear regression equation of the method for Co was A = 0.003 303c +0.004 218.The relative standard deviations were 4.1%(standard sample) and 1.1%(wheat sample 6#).The detection limit was 0.005 mg/kg. |
