建立了测定工业用甲醇和噻吩中硫、氯含量的离子色谱检测方法。样品经（700±25）℃灼烧后，残留物用蒸馏水洗涤，利用离子色谱仪进行分析。甲醇和噻吩中硫、氯检测结果的相对标准偏差为1.04%～1.26%，加标回收率为99.2%～101.2%。该方法操作简单，精密度和准确度高，可用于大部分可燃性有机化合物中硫、氯含量的检测。

The method was established for the determination of the content of sulfur and chlorine in industrial methanol and thiophene by ion chromatography method. After the sample being burned at (700±25)℃, the residue was washed with distilled water and analyzed by ion chromatography. The relative standard deviation of the results in the same solution were 1.04%-1.26%, the recoveries were 99.2%-101.2%. The method is simple with high accuracy and precision, and has a strong practical and propagable detection of the content of sulfur, chlorine of the most combustible organic compounds.
