AB  - In this work, magnetic carbon nanotubes (CNTs) were prepared by mixing the 
      magnetic particles and multi-walled carbon nanotubes dispersed solutions. Due to 
      their excellent adsorption capability towards hydrophobic compounds, the magnetic 
      CNTs were used as adsorbent of magnetic solid-phase extraction (MSPE) to extract 
      phthalate acid esters (PAEs), which are widely used in many consumable products 
      with potential carcinogenic properties. By coupling MSPE with gas 
      chromatography/mass spectrometry (GC/MS), a rapid, sensitive and cost-effective 
      method for the analysis of PAEs was established. Our results showed that the 
      limits of detection (LODs) of 16 PAEs ranged from 4.9 to 38 ng L(-1), which are 
      much lower compared to the previously reported methods. And good linearities of 
      the detection method were obtained with correlation coefficients (R(2)) between 
      0.9821 and 0.9993. In addition, a satisfying reproducibility was achieved by 
      evaluating the intra- and inter-day precisions with relative standard deviations 
      (RSDs) less than 11.7% and 14.6%, respectively. Finally, the established 
      MSPE-GC/MS method was successfully applied to the determination of PAEs from 
      bottled beverages, tap water and perfume samples. The recoveries of the 16 PAEs 
      from the real samples ranged from 64.6% to 125.6% with the RSDs less than 16.5%. 
      Taken together, the MSPE-GC/MS method developed in current study provides a new 
      option for the detection of PAEs from real samples with complex matrices.
