-
摘要: 利用高频红外碳硫测定仪的高频燃烧红外吸收技术，测定了钨精矿中的硫。讨论了仪器分析过程，最佳助溶剂加入量等。该法测定范围：0.1 %~2.5 %，相对标准偏差小于2.1 %。Abstract: carbon-sulfur testing apparatus and high frequency burning infrared absorption technique are applied to determine the sulfur content in tungsten concentrate.The apparatus analysis and optimal solubilizer are discussed. The method can be used in the range at 0.01 % to 3.5 %, RSD < 2.1 %.
