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%.
