| 摘 要： | 采用气相色谱法分离单乙醇胺废液中单乙醇胺和其它杂质。方法采用HP-5色谱柱,标准曲线外标法测定单乙醇胺含量。单乙醇胺在1.61~17.73mg/mL浓度范围内与峰面积呈线性关系,回归方程:y=0.2776x-66.5264,相关系数为0.9998。平均回收率为99.20%,RSD为0.65%(n=6)。此方法简单、准确,便于单乙醇胺废液中单乙醇胺含量的测定。

| Abstract: | An efficient GC method for the determination of MEA and other impurities in waste monoethanolamine solution was established with HP-5 column based on external standard calibration curves.The linear range of the method was from 1.61 to 17.73 mg /mL for MEA.The regression equation was y=0.277 6×x-66.526 4 with r= 0.999 8.The average recovery was 99.20% with RSD 0.65%（n=6）. |
