Determination of Phosphorus and Manganese in Tea by Microwave Plasma Torch Atomic Emission Spectroscopy (MPT-AES)

Peihong LIANG and Anmo LI College of Chemisty and Molecular Engineering,Peking University,100871 Beijing  
A new method,microwave plasma torch atomic emission spectroscopy (MPT AES),was used to determine trace elements phosphorus and manganese in different tea.The detection limit of Mn and P are 8 ng·mL -1 and 95 ng·mL -1 respectively.By comparing this method with ICP AES we have drawn some conclusions.
