| 摘 要： | 通常采用燃烧--中和法或燃烧-碘量法测定铁矿物中硫含量,这些测定方法耗时长,矿样熔融不完全,导致测定结果不稳定.尝试采用HCS-216A高频红外碳硫仪测定,在试验条件下,该法测定硫含量为1.18%、1.84%的标样,测定值为1.181%、1.844%,相对标准偏差(RSD)小于0.35%(n=9).采用本法与常规燃烧中...

| Abstract: | Sulfur content in iron ores was determined by the combustion neutralization and the combustion iodometric method,the common practice needed much more time to determine sulfur content in iron ores,sometimes the samples were fused incompletely.The values resulted from the factors were instability.A method for the determination of sulfur content in iron ores was established by high frequency infrared absorption spectrometry HCS-216A.Using the standard samples,the results of 1.181% for 1.18% and 1.844% for 1.84% were measured by the proposed method,respectively.The relative standard deviation was less than 0.35%(n=9).Satisfactory analysis showed that there was significant consistency between the proposed method and common practice in 10 samples.The proposed method with effective,fast response and accuracy provided good application prospect in the analysis of iron ores. |
