| Abstract: | s:Six kinds of metals in Ampelopsis megalophylla,including Fe,Cu,Mg,Ca,Mn and Zn,were determined by flame atomic absorption spectrometry in this paper.The samples were digested by microwave with HNO_3 and H_2O_2,and then the content was determined according the calibration curve.The results showed that there were abundant essential elements in A mpelopsis grossedentata and its recoveries were 98.50%～100.70%.In a conclusion,this simple and accurate method could obtain a satisfactory result. |
