摘　　要：建立了顶空气相色谱法测定水中四氢呋喃的方法，优化了影响水中四氢呋喃顶空分析的温度、萃取时间和加盐量等因素。实验结果表明，在0．10—10．0mg／L范围内线性关系良好，方法检出限为0．02mg／L，相对标准偏差不低于6．9％，空白加标回收率范围为92．3％-107％。A new method for the determination of tetrahydrofuran in water by using HS - GC was developed. The influence of headspace temperature, time and NaCl dosage were studied, linear calibration curves were obtained for tetrahydrofuran in range be- tween 0.10 mg/L and 10.0 mg/L. The detection limit of this method was found to be 0.02 mg/L and RSD was no less than 6.9%. The results showed that the average recovery rate of five parallel tests was 92.3% - 107%.
