用铅离子选择性电极间接测定废水中Cr(Ⅵ)及Cr(Ⅲ)

Determination of Cr ( Ⅵ ) and Cr ( Ⅲ ) in Electrop It ing's Wasted Water by Lead Electrode Indirectly

本文介绍了测定废水中Cr(Ⅵ)及Cr(Ⅲ)的一种新方法——铅离子选择性电极法。与火焰原子吸收法比较,该法测定结果与其一致。

In this paper, a new determimation' s method about Cr(Ⅵ)and Cr(Ⅲ)in wasted water, Lead electrode method, is introduced. Compare with flame atomic absorption method, This method's result is Same.
