摘要
本文采用微波消解方法处理减肥茶样品后,用ICP-MS法测定样品中铅、汞、镉、砷、铜重金属元素的含量,通过优化ICP-MS仪器测定条件,用内标克服仪器信号漂移及样品基体效应等的影响,建立了ICP-MS法同时测定减肥茶中多种元素的方法,同时对市场上不同厂家及不同批次的7例样品重金属的污染状况进行了评估,为健康安全使用减肥茶提供有益参考。
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.
