高频红外分析法同时测定煤中碳和硫

摘要

报道了高频红外分析仪同时测定煤中碳和硫的方法，可测w(C)为0%～80%，w(S)为0%～2.0%。方法经国家一级标准物质分析验证，结果与标准值相符，相对标准偏差(RSD,n=8)C<1.7%,S<1.3%。%A method for simultaneous determination of carbon and sulfur in coal samples by HFIR C/S analyzer is described in this paper. The proposed method provides a wide concentration range for carbon (w=0%～80%) and sulfur (w=0%～2%). The method has been verified by the determination of carbon and sulfur in standard reference coal samples. The results are in agreement with certified values with precision (n=8) of<1.7% RSD for carbon and <1.3% RSD for sulfur.
