TI  - [Rapid determination of six preservative residues in fruits and vegetables by 
      high performance liquid chromatography using dispersive solid phase extraction].
PG  - 170-3
AB  - A dispersive solid phase extraction-high performance liquid chromatographic 
      (HPLC) method was established for the simultaneous determination of 2,4-D, 
      thiabendazole, 2-naphthol, o-phenyl phenol, diphenyl ether and biphenyl in the 
      fruits and vegetables. The samples were vortexed for extraction with acetonitrile 
      containing sodium chloride and anhydrous magnesium sulfate. The acetonitrile 
      extraction was purified by acidic alumina dispersed solid phase extraction. The 
      analysis was performed on an Agilent TC C18 column (250 mm x 4.6 mm, 5 microm) 
      and an ultraviolet detector at 235 nm with a mobile phase of methanol-0.02 mol/L 
      (pH 6) potassium dihydrogen phosphate solution, at a flow rate of 1.0 mL/min with 
      gradient elution. Good linearities were observed in the range of 0.5-20 mg/L with 
      correlation coefficients greater than 0.99. The average recoveries of the six 
      preservatives in fruits and vegetables were in the range of 84.2% -99. 1% at 
      three spiked levels of 1, 2 and 10 mg/kg (n = 6) and the relative standard 
      deviations (RSDs) were in the range of 1.67%-10.3%. The limits of quantification 
      were 1 mg/kg. This method is simple, accurate and suitable for the determination 
      of the six preservatives in fruits and vegetables.
