| Abstract: | Tea samples were digested by HCI - HCIO4 solution in a microwave system,and then ICP- AES was applied to the determination of some trace elements in the samples.The proposed method is sim- ple and rapid with little contamination.The recovery is 90.2% - 106.3%, and the RSD is 1.7%- 6.2%. |
