摘要
用火焰原子吸收光谱法测定了茶叶中锂元素的含量。并比较了两种消解茶叶方法的测定结果。实验结果表明，干法比湿法效果要好得多，干法消解的回收率在９２２％～９６１％之间。
Lithium in tea was determined by flame atomic absorption spectroscopy (FAAS).The results achieved by two sample digestions are compared.It is shown experimently that the ashy_digestion method is superior to watery_digestion method.The recovery ratio of the ashy_digestion is 92 2%～96 1%.
