[Study on determining cadmium and arsenic in rice and flour by different digestion manner].
Cadmium and arsenic in rice and flour was determined by microware digestion and direct digestion with electrothermal board. Mastering the characters of the pre-disposal mode for these samples, and depending on the phenomena during the experiment and the results determined by the machine, the authors can analyse the merit and disadvantage of the different digestion mode to find out the most excellent conditions and methods for experiment, then give out reasonable and applicable method based on unsuccessful experiments, analyse the reasons for unsuccessful experiments, and perfect two digestion methods which the authors used to determine cadmium and arsenic.
