摘要
对SnC l2-TiC l3-K2Cr2O7(CuSO4催化)法测定铁矿石中铁含量的条件进行了优化,并将本法与有汞法、稀K2Cr2O7法和甲基橙法进行了比较,结果发现,该法的实验现象明显,操作方便,污染少,准确度高,精密度好。
A method of detcrmination of iron content in iron ores by starmous chloride - titanium （Ⅲ） chloride - potassium dichromate using CuSO4 as catalyzer was investigated and optimized. Under the optimal conditions, the established method was compared with mercury method, K2Cr2O7 medlod and methyhc - orange method. The results revealed that this method showed advantages, such as obvious phenomenon, simple operation, less contamination, high accuracy and good precision.
