摘要：
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 15 minutes. The determination limits (S/N =3) of each CP derivative were the range of 0.2-2.1 mu g L-1 in the volume ratio 1000 (ie. water phase: 50 mL-->organic phase: 50 mu L) Ten kinds of CP derivative were completely separated and were able to determine except 2,5CP and 2,6CP.
