AB  - In this study, a new magnetic ionic liquid (MIL) was designed and prepared, 
      containing a magnetic cation from the ligand N,N-dimethyl biguanide (DMBG) 
      complexing with magnetic center Co(2+) and a bis-trifluoromethanesulfonimide 
      (NTf(2)(-)) anion. Using the MIL as the extraction solvent, a salting-out 
      assisted dispersive liquid-liquid microextraction (SA-DLLME) combined with high 
      performance liquid chromatography-ultraviolet detection (HPLC-UV) was established 
      for the enrichment and detection of four parabens in environmental water samples. 
      The one-factor-at-a-time experiment was employed to optimize the conditions 
      affecting the extraction efficiency. Under the optimized extraction conditions, 
      the limits of quantification (LOQs) of the four target analytes ranged from 2.0 
      ng mL(-1) to 2.8 ng mL(-1), and the coefficients of determination (R(2)) were 
      above 0.9996 in the linear range of 2.8-400 ng mL(-1). On the other hand, the 
      method displayed good repeatability and accuracy with intra-day and inter-day 
      relative standard deviations (RSDs) of 2.1-13.0% and recoveries of 82.0-114.6%. 
      The established method was applied to real samples with recoveries within 
      81.6-125.4%, and the results demonstrated that the method was practical.
