摘要

Ultrasonic extraction and purification using solid-phase microextraction column for the determination of 7 types of organochlorine pesticides including α, β, γ, δ-BHC, 2,4 '-DDT, 4,4'-DDT and heptachlor from the Saussrrea cotus were investigated in this study. The pretreatment of Saussrrea cotus samples, the effect of different ultrasonic time on the extraction efficiency and the effect of different ratio of dichloromethane: petroleum ether on purification efficiency were studied. Results show that the satisfactory extraction conditions for pre-treatment process are: 30 minutes ultrasonic treatment; the volume ratio of dichloromethane and petroleum ether mixture is 3:7.
