AB  - A planar graphene oxide-based magnetic ionic liquid nanomaterial (PGO-MILN) was 
      synthesized. The prepared PGO-MILN was characterized by transmission 
      electronmicroscopy (TEM) and Fourier-transform infrared spectrometry (FTIR). The 
      results of adsorption experiments showed that the PGO-MILN had great adsorption 
      capacity for 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), 
      2,4,6-trichlorophenol (2,4,6-TCP), 2,3,4,6-tetrachlorophenol (2,3,4,6-TeCP) and 
      pentachlorophenol (PCP). Based on the adsorption experimental data, a sensitive 
      magnetic method for determination of the five CPs in environmental water samples 
      was developed by an effective magnetic solid-phase extraction (MSPE) procedure 
      coupled with high-performance liquid chromatography-tandem mass spectrometry 
      (LC-MS/MS). The effects of main MSPE parameters including the solution pH, 
      extraction time, desorption time, and volume of desorption solution on the 
      extraction efficiencies had been investigated in detail. The recoveries ranged 
      from 85.3 to 99.3% with correlation coefficients (r) higher than 0.9994 and the 
      linear ranges were between 10 and 500ngL(-1). The limits of detection (LODs) and 
      limits of quantification (LOQs) of the five CPs ranged from 0.2 to 2.6ngL(-1) and 
      0.6 to 8.7ngL(-1), respectively. The intra- and inter- day relative standard 
      deviations (RSDs) were in the range from 0.6% to 7.4% and from 0.7% to 8.4%, 
      respectively. It was confirmed that the PGO-MILN was a kind of highly effective 
      MSPE materials used for enrichment of trace CPs in the environmental water.
