A novel method for determination of organochlorine pesticides residuals (2,4-DDT and 4,4-DDT) in water samples through hollow fiber membrane-liquid phase microextraction using ionic liquid material as extractant coupled with high performance liquid chromatography has been developed. The effect of extraction parameters including pH of the feed solution, stirring rate and extraction time was investigated. The proposed method provided enrichment efficiency of 323 and 289 for 2,4-DDT and 4,4-DDT respectively. The method had good linear range of 0.5-50 μg /L and the limits of detection of the pesticides were 0.1 μg /L.
