[Determination of phosphorus and manganese in tea by microwave plasma torch atomic emission spectroscopy (MPT-AES)].
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.
