原子荧光光度法测定几种市售红茶中砷的含量

Determination of Arsenic in Black Tea Products by Atomic Fluorescence Spectrometry

采用微波消解和浸泡法分别处理红茶样品,通过原子荧光光度法检测了几种市售红茶中砷的含量。结果表明不同的处理方法,砷含量虽有所不同,但所测样品砷含量都没有超出国家限量,符合安全饮用标准。

In this paper,the contents of heavy metal arsenic in several commercially sold black tea were determined by atomic fluorescence spectrometry.The tea samples were treated by microwave digestion and soaking.The results show that the arsenic contents in samples don't exceed the national limit,which conform to the drinking safety standard.
