Abstract
In this paper, an apparatus of inert gases-surfactants assistant liquid-liquid extraction(ISALLE) is described. Based on this apparatus, a method for the determination of 20 trace level organochlorine pesticides in the water was developed. The influence of various experiment conditions on the extraction efficiency of ISALLE for the organochlorine pesticides was studied. The linearity in the detecting range is good (R≫0.99) with the detection limits of 0.4-2 ng/L¿and the quantification limits of 4-8 ng/L¿The RSDs were lower than 6.7¿ and the recoveries were 83%-121%. The method had been used to determine the organochlorine pesticides in the surface water with satisfactory results.
