运用顶空固相微萃取与色谱联用方法(HS-SPME-GC)对水中的残留有机氯化合物进行了分析.对影响HS-SPME-GC分析灵敏度的各种实验因素如涂层种类、萃取温度、平衡时间、离子浓度等进行了讨论,并将该方法与固相萃取法(SPE)、液液萃取法(LLE)作了对比;同时考察了常见环境共存污染物直链烷基苯磺酸钠(LAS)对几种方法的影响.
The residual organic chlorine compounds in water were analyzed by headspace solid-phase microextraction coupled with chromatography (HS-SPME-GC), and various experimental factors influencing the sensitivity of HS-SPME-GC analysis such as coating type, Temperature, equilibrium time and ion concentration were discussed. The method was compared with SPE and liquid-liquid extraction (LLE). At the same time, the effects of common environmental pollutants such as linear alkyl benzene sulfonates Effect of sodium acid (LAS) on several methods.
