A novel method was described for the rapid determination of atrazine using dispersive liquid phase microextraction in combination with high performance liquid chromatography (HPLC). Possible impact parameters such as sample pH, extraction and disperser solvents, salting-out effect, and extraction time were investigated. The experimental results indicated that proposed method possessed an excellent analytical performance. The linear range, detection limit, and precision (R.S.D.) were 0.1-50 ng mL^-1 (R₂=0.9955), 0.601 ng mL^-1 and 6.4%, respectively. The proposed method was validated with the real water samples,and the spiked recoveries were in the range of 69.9-89.8%, respectively. These results indicated that the established method with high enrichment factor, short extraction time was an excellent alternative for the routine analysis of atrazine in environmental samples.
