The simple pretreatment-GC/MS method for chlorophenol(CP) derivatives was developed using the homogeneous liquid-liquid extraction in water/pyridine/ethyl chloroacetate ternary component system. The proposed method was performed all process of pretreatment within 15minutes. The determination limits(S/N=3) of each CP derivative were the range of 0.2-2.1μgL-1 in the volume ratio 1000(i.e. water phase: 50mL→organic phase: 50μL). Ten kinds of CP derivative were completely separated and were able to determine except 2, 5CP and 2, 6CP.
