本文描述了水中微量芳胺的气相色谱分析方法。胺类与五氟苯甲酰氯在1％碳酸氢钠溶液中直接反应,衍生产物经甲苯萃取后进行GC/ECD分析。取样100ml时,不同胺类的最低检测浓度为20—50ppt。回收实验表明,当胺加入量为2—114ppt时,方法的回收率为83.9—95.4％,最大相对标准偏差为9.11％。 This article describes the gas chromatographic analysis of trace aromatic amines in water. Amines were directly reacted with pentafluorobenzoyl chloride in 1% sodium bicarbonate solution. The derivatized products were extracted with toluene and analyzed by GC / ECD. Sampling 100ml, the lowest concentration of different amines detected 20-50ppt. Recovery experiments showed that when the amount of amine added was 2-114ppt, the recovery rate of the method was 83.9-95.4% with the maximum relative standard deviation of 9.11%.
