对无汞法测定全铁的改进

Improving the Method of TiCl3-K2Cr2O7 Titration for the Iron Content in Iron Ore

三氯化钛-钨蓝重铬酸钾滴定法是一种准确测定铁矿石中全铁的方法。但它不完全适用于本矿矿石,我们在溶解、还原等方面进行改进,改进后的方法准确、简便、实用。

TiCl3-tungstenblue-dichromate titration is an accurate method of determining the total iron content in iron ore.But it is not very adapted to our iron ore. We improved it in melting, reducing and so on.The improved method proved to be accurate,simple and adapted.
