摘要
建立了气相色谱法测定早强剂中三乙醇胺的方法。本方法的相对标准偏差（RSD）≤2．32％，回收率在93．5％-103．7％，三乙醇胺的方法检出限为0．5mg／kg，是首次采用气相色谱仪对水泥早强剂中的三乙醇胺进行分析的一种方法。
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.
