AB  - A novel magnetic solid-phase extraction (MSPE) technique coupled with ultra 
      performance liquid chromatography (UPLC) has been developed for the determination 
      of four sulfonylurea herbicides (sulfosulfuron, bensulfuron-methyl, 
      pyrazosulfuron-ethyl and halosulfuron-methyl) in aqueous samples. The key point 
      of this method was the application of a novel magnetic nanomaterial (Fe(3)O(4) @ 
      PDA-DES). The functional groups, morphology, and magnetic properties of this 
      magnetic nanomaterial were investigated through fourier transformed infrared 
      spectroscopy (FT-IR), scanning electron microscopy (SEM), vibrating sample 
      magnetometer (VSM), and X-ray diffraction (XRD) respectively. The main factors 
      which could affect the experiment results were optimized. Under the optimum 
      conditions, the linearity of this method ranged from 5.0-200 mug L(-1) for all 
      analytes, with correlation coefficients (r) >/=0.9901. The enrichment factors were 
      between 495 and 630, and the relative standard deviations (RSDs) were less than 
      3.6%. The limits of detections (LODs) varied from 0.0098 to 0.0110 mug L(-1). In 
      the final experiment, the developed method has been successfully applied to the 
      determination of sulfonylurea herbicides in environment and drinking water 
      samples, and the obtained recoveries were between 61.3% and 108.6%.
