Triethylamine is slightly soluble in water, alkaline, and has a strong irritant effect on the respiratory system, which can easily cause pulmonary edema. Long term consumption of water sources rich in triethylamine poses a potential threat to human health. The GB 5749-2022 Sanitary Standards for Drinking Water does not specify any requirements for the limit of triethylamine.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses 5% squalane; 2% potassium hydroxide/Chromosorb103 (80-100 mesh); A headspace gas chromatography method was established to determine the concentration of triethylamine in water using a glass column In a constant temperature sealed container, triethylamine in the water sample is distributed between the gas and liquid phases until equilibrium is reached when it is strongly alkaline. The gas phase sample above the water sample is taken and detected using gas chromatography hydrogen flame detector (FID). The concentration of the analyte in the sample is determined by external standard method Experiments have shown that under alkaline conditions, triethylamine has good response linearity when tested by headspace gas chromatography, with a correlation coefficient greater than 0.998. The addition of inorganic salt sodium chloride can significantly improve the detection sensitivity, and the lower limit of determination can reach 0.58mg/L

三乙胺微溶于水，呈碱性，对呼吸系统具有强烈的刺激性，容 易引起肺水肿，长期饮用富含三乙胺的水源，对人类健康构 成潜在威胁。《GB 5749-2022 生活饮用水卫生标准》中未对 三乙胺限量指明要求。
浩瀚色谱（山东）应用技术开发有限公司，采用5%角鲨烷;2%氢氧化钾/Chromosorb103(80目~100目);玻璃柱建立了测定水中三乙胺浓度的顶空-气相色谱法.在恒温的密闭容器中,强碱性时水样中的三乙胺在气、液两相间分配直至达到平衡,取水样上方气相样品,使用气相色谱-氢火焰检测器(FID)进行检测,通过外标法测定样品中待测物质浓度.实验表明,在碱性条件下,三乙胺采用顶空气相色谱法测试时具备良好的响应线性,相关系数＞0.998.加入无机盐氯化钠后可以显著提高检测灵敏度,测定下限可以达到0.58mg/L.
