HgCl_2浸取法测定钢渣中的单质铁

Determination of Fe^0 in Steel Slag through Dissolution in HgCl_2 Solution

提出了钢渣中单质铁的测定方法———HgCl2 溶液浸取 ,K2 Cr2 O7滴定。回收率为 95%～ 99% ,RSD为 0 .6%。

In this study, the Fe 0 in steel slag was dissolved in HgCl 2 solution and then titrated with K 2Cr 2O 7 solution. The recovery rate of Fe could get to 95%～99% with the new method, And RSD was 0.6%. The result was satisfactory.
