| Abstract: | A microwave acid-digestion system was developed for determining As and Hg accurately.The accuracy and precision was verified by using national standard substances of poplar leaves,spinach and wheat powder,the results was shown to be satisfactory.Recovery was in the range of 92.1%～106.2%.Precision of the method was 1.7%～4.7%.This analysis method was simple,fast and accurate with the value of populizing and applying. |
