| Abstract: | Inductively coupled plasma mass spectrometry （ICP-MS） with microwave digestion was applied to determine chromium, cobalt, nickel, copper, arsenic, lead, cadmium, manganese, iron, zinc, strontium simulta- neously in Herb Tea. We researched on detection limit and linear range, experimented labeled recovery and accuracy Using internal standard method. It indicated that the method is simple, rapid, accurate which can meet the demand for the determining heavy metal elements in Herb Tea. |
