Abstract :
This essay established the determination of cadmium content in the food paper and plastic packaging materials with wet digestion-flame atomic absorption spectrometry. The detection limit and relative standard deviations of cadmium were 0.0056 μg/ml and 1.93%. The recoveries of cadmium ranged from 91.92% to 96.37%. The method has the advantages of low detection limit, high accuracy and good precision.
