AB  - This work proposes an application of amine-functionalized metal-organic framework 
      (NH(2)-MIL-101(Fe)) as sorbent for dispersive micro-solid phase extraction 
      (D-muSPE) of ten priority phenolic pollutants. The sorbent was simply synthesized 
      under facile condition. The entire D-muSPE process was optimized by studying the 
      effect of experimental parameters affecting the extraction recovery of the target 
      analytes. The final extract was analyzed using high performance liquid 
      chromatography with photodiode array detector. Under the optimum condition, the 
      proposed procedure can be applied for wide linear calibration ranges between 
      1.25-5000 mug L(-1) with the correlation coefficients of greater than 0.9900. The 
      limits of detection (LODs) and limits of quantitation (LOQs) were in the ranges 
      of 0.4-9.5 mug L(-1) and 1.25-30 mug L(-1), respectively. The precision evaluated 
      in terms of the relative standard deviations (RSDs) of the intra- and inter-day 
      determinations of the phenol compounds at their LOQ concentrations were below 
      13.9% and 12.2%, respectively. High enrichment factors up to 120 were reached. 
      The developed method has been successfully applied to determine phenol residues 
      in environmental water samples. The satisfactory recoveries obtained by spiking 
      phenol standards at two different concentrations (near LOQs and 5 times as high 
      as LOQs) ranged from 68.4-114.4%. The results demonstrate that the 
      NH(2)-MIL-101(Fe) material is promising sorbent in the D-muSPE of phenolic 
      pollutants.
