摘要
测定锰矿石中铁含量，采用盐酸和硫酸溶样，盐酸和氨水调节pH至1．5-2，趁热加磺基水杨酸指示剂，用EDTA标准溶液滴定。操作简便快速，结果稳定准确，适用于行业、矿山快速分析。
We have made a determination of iron content in manganese ore, hydrochloric and sulfuric acid to dissolve sample, hydrochloric acid and ammonia, by adjusting pH to 1.5 - 2 to strike sulfosalicylie acid indicator with EDTA titration solution. This is a simple and rapid operation to be a stable and accurate result, as will be suitable for industry, mining rapid analysis.
