%X 本文简述了测定铁矿石中全铁三种测试方法并进行了比对，选择了三氯化钛–重铬酸钾–中性红指示剂法，实验研究了温度、溶样酸、介质酸、指示剂的选择及共存离子的消除，避免了汞带来的危害，取标样分析结果非常满意。<br />
Three methods for determination total iron in iron ore were described and compared in this paper. The tita-nium trichloride, potassium dichromate and neutral red were selected as indicator. At the same time, the temperature, solution acid, medium acid, the selection for indictor and elimination of coexisting were all studied in this experiment, while the hazards posed by mercury was also avoid. At last, the results for analysis standard samples were very satis-factory.
