摘要
应用气相色谱法,建立了焦炉煤气中苯及甲苯含量的分析方法。该方法的相对标准偏差小于0.59%(n=5),回收率99.6%~102.0%,具有分析耗时少,操作便捷的优点。对于及时优化生产工艺,提高企业经济效益,具有积极的指导意义。
Application of gas chromatography method,analytical method of benzene and toluene content in coke oven gas was established.The RSD of the method were less than0.59%(n=5),and the recoveries were 99.6%~102.0%.And this method has the advantages of less analysis time and simple operation.This method has positive guiding significance for optimized production process in time and improved to the economic benefits of enterprises.
