| Abstract: | Established the method of determination for triethanolamine in early strength agent by gas chromatography. The relative standard deviati6n （RSD） for this method was ≤ 2.32%, recovery between 93.5% - 103.7%, triethanolamine detection limit was 0. 5mg/kg. This method is applicable to the cement thickening in the analysis of triethanolamine using gas chromatography for the first time. |
