摘要
把水中的铜富集后 ,在与火焰原子吸收法相结合 ,提高了方法的灵敏度 ,操作简便 ,检出浓度 1ug·L- 1 ,相对标准差为 3.2 %,回收率为 96 .3%～ 10 2 .8%。
A FAAS method for the determination of copper in water samples was reported in this paper. The floatation technigue was used for the preconcentration of the above mentioned metal ions. It proved to be sensitive and easy to manipulate with satisfactory recovery and precision. The limit of detection for copper was 1 ug·L -1 and a RSD of 3.1 %?the rang of 96 %～99 % was obtained.
