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0.25~50.0×103 ng/L范围内线性较好, 检出限为0.04~3.58×103 ng/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%.

Abstract:

This paper studies an analytical technique of 30 halogenated hydrocarbon compounds 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 0.25~50.0×103 ng/L, with good linearity. The detection limit is 0.04~3.58×103 ng/kg. Blank standard addition recovery is 62.7%~122.0%, and relative standard deviation (RSD) is 0.7%~14.9%.
