摘　　要：介绍了一种新型的分析燃料煤中全硫含量的方法——艾士卡-离子色谱法。该方法结合了艾士卡法和离子色谱法的优点,避免了传统艾士卡法的操作步骤复杂和精密度较低的问题。同时,该方法与目前广泛使用的库仑滴定法在检测煤的全硫含量的结果上无显著性差异,因此对于St<1.00%的煤样,艾士卡-离子色谱法可以一定程度上代替库仑滴定法。这一方法的提出为燃料煤全硫含量的分析提供了一种更加高效、准确的手段。A new method for the analysis of total sulfur content in fuel coal,Eska-ion chromatography,is in⁃troduced.This method combines the advantages of Eska method and ion chromatography,and avoids the problems of complicated operation steps and low precision of traditional Eska method.At the same time,there is no significant difference between this method and the widely used coulometric titration in the detec⁃tion of total sulfur content of coal.Therefore,for the coal samples with St<1.00%,Eska-ion chromatography can replace coulometric titration to a certain extent.The proposed method provides a more efficient and ac⁃curate means for the analysis of total sulfur content in fuel coal.
