AB  - In this work, a new analytical method based on polydopamine functionalized 
      magnetic graphene (PDA@MG) adsorbent material has been developed to determine 
      three triazole fungicides in water samples. As previous step, a novel 
      polydopamine functionalized PDA@MG adsorbent material has been successfully 
      prepared, which was characterized by fourier transform infrared spectroscopy 
      (FT-IR), scanning electron microscopy (SEM), transmission electron microscope 
      (TEM), and vibrating sample magnetometer (VSM). Based on this novel material, a 
      new magnetic solid phase extraction (MSPE) method coupled with high performance 
      liquid chromatography (HPLC) has been established for the determination of 
      triazole fungicides in water samples. The main factors which could affect the 
      experimental results were optimized. Under the optimal conditions, good linarites 
      has been achieved in the range of 0.2-50 microg L(-1), with the correlation 
      coefficients (R(2)) were between 0.9962 and 0.9996. The limits of detections 
      (LODs) were 0.0048-0.0084 microg L(-1), and the relative standard deviations (RSDs) 
      were between 1.7% and 4.8%. In addition, enrichment factors (EFs) were 572-916 
      times, which showed triazole fungicides residues could be accurately extracted 
      and analyzed in this way. In the final experiment, the established method was 
      applied to the detection of target analyzes in water samples. Satisfied results 
      could be obtained for tebuconazole, propiconazole, and flusilazole. The 
      recoveries of five water samples were between 69.4% and 106.4%, and the RSD were 
      between 1.0% and 6.5%. The development method is more easy, effective, green and 
      environmental-friendly, and has potential for application.
