湘潭师院北院地下水中锌含量的测定

Determination of the content of Zn^(2+) in underground water in north campus of Xiangtan Normal University

用双硫腙萃取光度法和火焰原子吸收光谱法分别测定了湘潭师院北院地下水中的锌。两种方法的结果 ,经检验 ,无显著性差异。锌含量为 0 .2 9mg/L 。

Both methods for the determination of Zn 2+ in underground water in north campus of Xiangtan Normal University are proposed in this paper. The methods are spectropho tometry with dithizone extractiving and flame atomic absorption spectroscopy.The result by comparing these two experiments indicates that there is no appreciable difference.The content of Zn 2+is 0.29 mg/L,which accords with the standard of the State.
