In this paper,microwave digestion approach to weight-reducing tea samples,with the weight-reducing tea by ICP-MS determination of lead,mercury,cadmium,arsenic,copper heavy metal content.By optimizing the conditions for ICP-MS instrument measured using an internal standard to overcome the instrument drift and sample matrix effects,the establishment of the ICP-MS method for simultaneous determination of many elements in weight-reducing tea.Furthermore, the contamination of heavy metals in severa1 commercial available weight-reducing teas were evaluated which can provide valuable references for the healthy.
