摘要
研究采用高温燃烧红外吸收法测定钢精矿中高硫的方法。与经典的硫酸钡重量法及高温燃烧中和法相比,新方法 具有快速、准确、简便等优点。可测定铜精矿中10％～35％的高硫,相对标准偏差(RSD,n=8)小于1.0％。
The method for rapid determination of total sulfur in copper concentrates by IR-absorption spectrometry is investigated. The novel measure is rapid, accurate and simple in comparison with classic method. The measuring range is 10% -35% and RSD ( n = 8) is less than 1.0% .
