摘要
采用火焰原子吸收方法连续测定了茶叶中铅、铜、锌、镉的含量 ,方法灵敏、准确。测定时无需富集、萃取 ,操作简便 ,回收率 93 0 %～ 98 1 % ,相对标准偏差不超过 5 3 %。
A method for the continuous determination of Pb,Cu,Zn,Cd in tea by flame atomic absorption spectrophotometry(FAAS)has been developed with high sensitivity and fine accuracy.Preconcentration and extraction are not necessary for the determination,so the method is rapid and easy to operate.The recovery was 93 0%～98 1%,and the RSD was not more than 5 3%
