摘要
利用高频红外碳硫仪对磁铁矿、烧结矿及球团矿等铁矿中硫含量的测定进行了研究。采用纯铁、样品、钨粒助熔剂的添加顺序,对仪器精密度、准确度进行考查,相对标准偏差及相对误差均在国标允许范围内,加标回收率很好。
The determination of sulphur in iron ore was presented by the use of high-frequency IR carbon sulphur analyzer.The proper method was used,thus the accuracy and stability of the instrument were enhanced.The relevant standard deviation and relevant error were in the range of the extent permitted in GB,and the recovery obtained was satisfactory.
