Abstract This paper describes a new method for the rapid and sensitive analysis of atrazine and simazine based on the dispersive liquid-liquid microextraction with carbon tetrachloride and methanol as the extraction solvent and disperser solvent. Under the optimal conditions, there are excellent linear relationships between the peak area and the concentration in the range of 0.5 - 50 microg L(-1) for atrazine and 0.1 - 50 microg L(-1) for simazine. The limits of detection were 0.1 and 0.04 microg L(-1) for atrazine and simazine, respectively. The proposed method was also applied to the analysis of real water samples, and excellent results were achieved with spiked recoveries in the range of 60.7 - 91.4\%. All these results demonstrate that the proposed method would be widely used in many fields in the future.
