两种煤中氯测试方法的对比研究

Comparison of Two Methods in Chlorine Content Testing of Coals

分别用氧弹燃烧法和艾氏卡试剂高温分解法对煤样进行前处理,用离子色谱法检测,建立了氧弹燃烧-离子色谱和艾氏卡试剂熔样-离子色谱两种煤中氯的检测方法。根据试验数理统计方法用标准煤(GBW11118)对该两种检测方法进行评定,测定值与标准值无明显差异,准确度良好。

Testing chlorine content in coals by method of Eschka reagent molten sampleion chromatography and oxygen bomb decomposition-ion chromatography.According to mathematical statistics,the measured value of two methods have not obvious difference compared with standard value.The result showed that the accuracy is satisfied.
