茶叶及浸泡液中锰含量的测定

Determination of manganese in tea leaves by Flame Atomic Absorption Spectrometry

采用火焰原子吸收分光光度法测定了几种茶叶中的锰含量，考查了不同的泡茶方式下锰的浸出率。表明茶叶中锰含量丰富，为172．0～397．6mg／Kg，饮茶对人体健康有益，茶汤中的锰浸出率约52．2％～85．5％。

The manganese in some kinds of tea leaves were determined by Flame Atomic Absorption Spectrometry. The result shows that tea leaves are less abundant in manganese, 172.0～397.6 mg/Kg. And the extracted rate is about 52.2%～85.5% in different methods.
