| 摘 要： | 为有效测定茶汤中有害重金属元素,文章采用电感耦合等离子体发射光谱(ICP-AES)法,测定了茶汤中的Cu,Fe,Mn,Zn,Cr,Cd等重金属元素含量。在回收试验中,铜的平均回收率为101%,镉的平均回收率为95.4%,锰的平均回收率为118%,镍的平均回收率为87.4%,铁的平均回收率为118%。实验结果表明:该方法快速简单,有助于推广和应用。

| Abstract: | To effectively detect harmful heavy metal elements in tea soup,inductively coupled plasma emission spectrometer(ICP-AES)was used to quickly determine heavy metals such as Cu,Fe,Mn,Zn,Cr and Cd content in tea soup.At the recovery test,average copper recovery was 101%,cadmium recovery was 95.4%,manganese recovery was 118%,nickel recovery 87.4% and iron recovery 118%.Experimental results showed that the method which was quick and easy will help to promotion and application. |
