摘要
采用P&T-GC/MS分析汉江水中挥发性有机物,选用无干扰纯净水和恒温吹扫捕集,提高了挥发性有机物分析的灵敏度、精密度和准确度.SPE-GC/MS分析汉江水中半挥发性有机物时,水样直接过C18小柱进行固相萃取,C18采用遮光处理,避免半挥发性有机物光解,提高了检测的回收率,监测到的25种半挥发性有机物的回收率为75%～91%.
Analytical methods for determining the volatile organic compounds （VOCs） and the semi volatile organic compounds （SVOCs） in Han River were developed. VOCs in water from Han River were purged and trapped by Tekmar 3000, then desorbed and analyzed by GC/MS. SVOCs in water from Han River were detected based on SPE-GC/ MS. The recoveries of 25 kinds of SVOCs were 75%-91%.
