摘    要:一种利用离子色谱来简化传统的重量法测定煤中全硫 ,将煤样与艾氏卡试剂 (Mg O+ Na CO3)混合灼烧 ,使煤中各种形态的硫全部生成可溶性的硫酸盐 ,用离子色谱法测定。两次重复测定结果的精密度和准确度完全符合要求 ,测定标准煤样的结果与标准值之差在规定误差范围内。离子色谱法测定煤样的结果与重量法所得结果比较相对偏差在0 .3 6%~ 1 .45 %之间 ,又经统计检验后认定二者无显著性差异。

关 键 词:煤中全硫  离子色谱法  重量法

Determine the TotaL Sulfur by lon Chromatography
Abstract:This paper introduce a new way to measure the total sulfur in coal by using ion chromatography.The total sulfur in coal can be determined by ion chromatography when it react with special reagent which made of MgO and NaCO3 nder high temperature and from soluble sulfate.The exactness and accuracy of the experiment results is satisfactory.The relative standard deviation of the results is 0.36 to 1.45 percent.There are no significant different between the results from he new method and that from the traditional gravity measurement.
Keywords:Total sulfur in the coal lon chromatographic Gravity measurement
