AB  - In this work, a sensitive analytical method based on packed-nanofiber solid-phase 
      extraction (PFSPE), after derivatization with trichloroacetic acid and 
      high-performance liquid chromatography with a fluorescence detector (HPLC-FLD), 
      has been established for the determination of aflatoxins (AFs) in milk. 
      Polystyrene polymeric multi-walled carbon nanotube (PS-MWCNT/OH) composite 
      nanofibers were fabricated by electrospinning and used to prepare homemade 
      extraction columns. The extraction efficiency of the HPLC-FLD analysis method was 
      sufficiently investigated and validated. After the implementation of optimal 
      conditions, all of the analytes were separated efficiently and the components of 
      the milk matrix did not disturb the determination. The obtained linear ranges of 
      the calibration curves were 0.2-20 ng/mL for AFTB1 and AFTG2, 0.1-10 ng/mL for 
      AFTB2, and 0.4-40 ng/mL for AFTG1. The recoveries ranged between 80.22% and 
      96.21%. The relative standard deviations (RSDs) for the intra-day and inter-day 
      results ranged from 2.81-6.43% to 3.42-7.75%, respectively. Generally, 11 mg of 
      sorbent and 200 muL of elution solvent were used to directly extract all of the 
      AFs from the milk matrix. Reported herein is the first utilization of 
      PS-MWCNT/OH-PFSPE HPLC-FLD to simultaneously analyze the occurrence of aflatoxins 
      in milk.
