摘要

Qualitative and quantitative analysis on phthalate plasticizes (DEHP, DIBP and DBP) of 24 kinds of common food paper packaging were carried out. The study determined the plasticizers using four kinds of organic extraction reagent named n-hexane, ethyl acetate, anhydrous ethanol, and acetone by the Ultrasonic extraction and the gas chromatograph-mass spectrometer technology. The best temperature, time and the way of the extraction of these four different reagent were obtained. Through experiments and analysis, the best extraction reagent of the plasticizers remained in the food paper packaging is ethyl acetate and the best way to extract targets is the combination of ultrasonic oscillation 30 min with vortex 3 min. For the extraction using ethyl acetate, the best temperature of the ultrasonic operation is 25 ℃, and the time of the optimum ultrasonic extraction is 90 min. The plasticizers were detected in all of the 24 kinds of food paper packaging samples by the method. The content of DEHP, DBP and DIBP were 0.33497-211.02104, 0.34484-519.9099, 0.20224-37.67883 mg/kg respectively. The result shows that the method is comparatively simple, fast and quantitative accuracy. But the safety of the food paper packaging should be concerned deeply.
