| titleOfInvention | Ultrasonic extraction-gas chromatography-mass spectrometry combined determination method for 8 phthalic acid esters in plastic food packaging material |
| abstract | The invention discloses an ultrasonic extraction-gas chromatography-mass spectrometry combined determination method of 8 phthalic acid esters in plastic food packaging materials, which adopts an ultrasonic-assisted extraction technology to extract the phthalic acid esters in the food packaging materials by using a mixed solvent of cyclohexane and ethyl acetate, and has a simple extraction mode; the extract is purified by gel permeation chromatography and then detected by gas chromatography and mass spectrometry. The method has the advantages of good selectivity, high sensitivity, simplicity, rapidness and accurate qualitative determination, and is successfully applied to the detection of the phthalic acid ester in the actual plastic food packaging material. |
