| 摘 要： | 建立了一种电感耦合等离子体质谱法测定玉桂茶泡剂中稀土元素的方法.在优化的条件下,15种稀土元素的检出限在0.00004～0.003 ng/mL范围,相对标准偏差在0.6%～2.6%范围.利用该方法分析了国家一级茶叶标准物质(GBW070605),结果与参考值一致.该方法被用于分析玉桂茶样品中的稀土元素,得到令人满意的结果. |

| Abstract: | A method has been established to determine trace rare earth elements in Cassia Tea Soaking Agent by inductively coupled plasma mass spectrometry. Under the optimized conditions,the detection limits are in the range of 0. 00004-0. 003 ng/mL range with the relative standard deviation of 0. 6%-2. 6%. Fifteen arre earth elements in SRM GBW 070605 tea sample were determined by the developed method,the determined value was in good agreement with the certified value. This method was utilized to determine rare earth elements in Cassia Tea Soaking Agent with satisfactory results. |
