气相色谱法测定克劳斯硫回收吸收液中二乙醇胺

Gas Chromatography Measure Claus Unit Sulfur Recovery Diethanolamine in Liquid

本文根据二乙醇胺的物理化学性质，研究建立了其气相色谱分析方法；通过对方法参数的选择和优化，确定了该方法的可行性，方法的相对标准偏差小于3%、加标回收率为99.92%～104.22%。结果表明，该方法可以准确测定水中二乙醇胺含量，为工艺参数调整提供有力指导。

This paper studies the establishment of the gas chromatography analysis method according to thephysical and chemical properties of diethanolamine,through the selection and optimization of method parame?ter and determine the feasibility of the method,the relative standard deviation of the method is less than3%,and the recovery of standard addition was 99.92% ~ 104.22;and the results show that the method canbe accurate determination of diethanol amine content in water and provide strong guidance for the adjustmentof process parameters.
