| 摘 要： | 拟定了一种快速简便的差减法来测定还原钛铁矿中的亚铁，即一份试样用三氯化钛－钨蓝重铬酸钾法测出全铁的百分含量Ａ；另一份试样用ＦｅＣｌ３溶液浸取，重铬酸钾滴定法测出金属铁的含量Ｂ。实验证明，还原钛铁矿中几乎不含高价铁，故（Ａ－Ｂ）即为亚铁的百分含量

| Abstract: | A rapid and simple determination of ferrous iron in reduced ilmenite was described. The percentage of total iron (A) in one sample was determined with TiCl 3-tungsten blue-dichromate method, and the metallic iron in another sample was dissolved by FeCl 3 solution. Its percentage (B) was determined with dichromate titration method. Tests showed that reduced ilmenite had no ferric iron, therefore, (A-B) was the percentage of ferrous iron. |
