摘要
本文采用中性红和二苯胺磺酸钠作指示剂,以重铬酸钾标准溶液对钒钛磁铁矿中钛铁连测.经对介质、指示剂、催化剂加入量等的优选试验和分析结果时照,本方法终点敏锐,操作简便、快速,结果可靠.
This paper deals with a method of successive determination of titanium and iron in V-Ti-magnetite by using neutral red and sodium diphenylamine sulfonate as an indicator and potassium dichromate as Standard solution.The preferred experiments on medium, indicator and catalytic agent amount,etc.and the analysis results show that the terminal point of this method is acute, operation is simple,convenient and fast,and the resulls are reliable.
