Abstract:
      A gas chromatography-mass spectrometry（GC-MS） method was established for the rapid determination of benzo（c）fluorene，benzo[b]naphtho[2，1-d]thiophene，5-methylphenanthroline and dibenzo[cd，jk]pyrene four polycyclic aromatic hydrocarbons（PAHs） in toys and children’s products.The results showed that using toluene as extraction solvent，ultrasonic extracting for 50 minutes，using DB-EUPAH capillary column，and selecting quantitative analysis in ion monitoring mode，four PAHs could be effective separated.The mass concentration testing linear range of four PAHs of this method was 0.01～1 mg·L-1，and linear correlation coefficient was not less than 0.999 2，the recovery rate was from 86.5% to 108.7%，and relative standard deviation was less than 3%.This method could be used for the rapid determination of four PAHs in toys and children’s products.
