In this study, a green, simple, and sensitive sample pretreatment procedure coupled with high-performance liquid chromatography (HPLC) was developed for the analysis of sulfadimidine (SM2) that exploits an aqueous two-phase system based on 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4) and ammonium sulfate ((NH4)2SO4) using a liquid-liquid extraction technique in real environmental water samples. The influences of the concentration of (NH4)2SO4, pH value, temperature, and concentration of SM2 on the extraction efficiency of SM2 were determined. Under optimal conditions, the extraction efficiencies of SM2 were over 93.7%. Calibration curves yielded good linearity (R 2=0.9998) over the range 3-240ngmL−1, and the limit of detection and limit of quantification for analytes were 0.9ngmL−1 and 3ngmL−1, respectively. The proposed method was successfully applied to the quantification of SM2 in water samples and recoveries were in the range of 101.2-107%.
