摘要
采用顶空固相微萃取(head space solid phase micro-extraction,HS-SPME)技术测定土壤中30种卤代烃类化合物,全面分析了影响目标物萃取效率的因素,确定了最佳萃取条件.采用顶空固相微萃取联合气相色谱法(HS-SPME gas chromatography,HS-SPME-GC)测定土壤中30种卤代烃化合物,该方法在0.25~50.0×103ng/L范围内线性较好,检出限为0.04~3.58×103ng/kg.空白加标回收率为62.7%~122.0%,相对标准偏差(relative standard deviation,RSD)为0.7%~14.9%.
This paper studies an analytical technique of 30 halogenated hydrocarbon com- pounds in soil using a method of head space solid phase micro-extraction （HS-SPME）, and analyzes influencing factors of target extraction efficiency. As a result, optimum extraction conditions are determined within 0.25-50.0× 10^3 ng/L, with good linearity. The detection limit is 0.04-3.58×10^3 ng/kg. Blank standard addition recovery is 62.7%-122.0%, and relative standard deviation （RSD） is 0.7%-14.9%.
