| 摘 要： | 以溴-甲醇浸溶,重铬酸钾法测定金属铁的准确度很高。但由于此法中要用到Br_2,CH_3OH,HgCl_2,K_2Cr_2O_7等对人体有害的试剂,本文采用I_2-C_2H_5OH浸溶,EDTA法测定,避免了使用以上有害物质。本方法简单,重现性好,终点易于观察,适用于钒钛高炉渣,高钛渣和普通炉渣中金属铁的测定。

| Abstract: | Great accuracy can be obtained when metal iron is determined with bromine for dissolution K2Cr2O7 for titration. Unfortunately, harmful substances such as Br2, CH3OH, HgCl2, K2Cr2O7 etc. must be used when this method. But these harmful substances can be avoided when I2-C2H5OH is used for dissolution and EDTA for titration as discussed in this paper. As this method is simple with good reapetability, it is suitable for the diterminat ion of metal iron slag containing V.Ti, in slag containing high Ti, and in common slags. |
