Abstract

In this paper, an apparatus of continuous flow solid-phase microextraction is described. Based on this apparatus, a method for the determination of 20 trace level organic chlorinated pesticides in the water was developed. The influence of various experiment conditions on the extraction efficiency of continuous flow solid phase microextraction for the organic chlorinated pesticides was studied. The linearity in the detecting range is good (R>0. 991) with the detection limits of 0.01-0.5 mugL-1, and the quantification limits of 0.02-1 mug/L. The RSDs were lower than 1% and the recoveries were 86%-118%. The method had been used to determine the organic chlorinated pesticides in the surface water with satisfactory results.
