AB  - Polydopamine (PDA)-coated magnetic multiwalled carbon nanotube (M-MWCNT) 
      composites were synthesized in two facile preparation steps, and were used as 
      adsorbents for magnetic solid-phase extraction (MSPE) coupled with 
      high-performance liquid chromatography (HPLC) for simultaneous extraction, 
      enrichment and determination of five kinds of typical chlorophenols (CPs) in 
      water samples. The as-prepared magnetic composites showed excellent magnetic 
      properties and high thermal stability. Various main parameters influencing the 
      extraction efficiency of MSPE were systematically investigated. Under the 
      optimized MSPE-HPLC conditions, a high enrichment factor (EF) was obtained in the 
      range of 85-112 for 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), 
      2,6-dichlorophenol (2,6-DCP), 2,4-dichlorophenol (2,4-DCP) and 
      2,4,6-trichlorophenol (2,4,6-TCP). Good linearity was obtained in the range of 
      2.0-200 mug L(-1) for 2-CP and 4-CP and 1.0-200 mug L(-1) for 2,6-DCP, 2,4-DCP and 
      2,4,6-TCP, with a correlation coefficient (R(2)) higher than 0.9964. The limits 
      of detection (LODs) and the limits of quantification (LOQs) were in the range of 
      0.10-0.31 mug L(-1) and 0.35-1.03 mug L(-1), respectively. The intraday and 
      interday precisions evaluated using relative standard deviation (RSD) values were 
      in the range of 1.05-2.25% and 1.88-2.83%, respectively. The validated MSPE-HPLC 
      method was also successfully applied to analyze five kinds of CPs in tap water, 
      lake water, river water and seawater samples, and satisfactory recoveries were 
      obtained in the range of 76.87-106.5% with RSDs of 1.64-6.78%.
