Determination of Metallic Element in Herb Tea by Inductively Coupled Plasma Mass Spectrometry

Inductively coupled plasma mass spectrometry（IC-MS）with dry ashing digestion was applied to determine arsenic，chromium，cadmium，lead，strontium，manganese，copper and zinc in Herb Tea.In addition，the recovery rate of standard addition was 90.3%～109.4％ and RSD was 1.38%～8.19％.It indicated that the method was simple，rapid，accurate which could meet demand for determining heavy metal elements in herb tea.
