不同品类乌龙茶中的稀土元素
Rare earth elements in different types of Oolong tea
摘要
Abstract
The concentrations of rare earth elements ( La, Ce, Pr, Nd, Sm, Eu, Gd, Td, Dy, Ho, Er, Tm, Yb, Lu, Y) in dif-ferent types of Oolong tea ( REOs) were investigated. The results showed that the total REOs (ΣREOs) of the samples ranged from 0.62 mg?kg-1 to 10.11 mg?kg-1 . The geometric mean of the varieties decreased in order of Tieguanyin>Minbei Shuixian>Yong-chun Foshou>Wuyi Shuixian>Wuyi Mingcong>Wuyi Rougui>Baiyaqilan>Zhangping Shuixian. The total light rare earth oxides (ΣLREOs) was significantly higher than heavy rare earth oxides (ΣHREOs) . La, Ce, Nd, and Y were the major rare earth ele-ments in the samples and the sum of the four elements occupied up to 80% of the total rare earth with Ce being the predominant one among the rare earth elements. Both ΣLREOs and ΣHREOs were significantly correlated with ΣREOs, respectively. However, no significant correlation between ΣLREOs and ΣHREOs was found.关键词
