| Abstract: | The mass and trace metal element contents in the plant had to be measured in grade estimation of farm enviroment. Microwave digestion and ICP-AES were dsed to analyze the heavy meatl elements in the plant. The method had many advantages such as high analytical speed and broad linear range etc. The detection limit of fifteen masss and trace meatal elements inclading K, Ca, Mg,Cu,Zn, Fe, Mn, Al, Cd, Cr, Mo, P, Pb, S, and, Si in the plant and the uncertain error estimation during the measuring were studided by using microwave digestion and ICP-AES. Which supplide the theoretical foundation for the measure determination of metal elements in many plant samples. |
