| Abstract:Phthalate plasticizers in coated papers were microwave-assisted extracted using acetone as the extraction solvent, and then were analyzed by gas chromatography-tandem mass spectrometry(GC-MS). Therefore, an effective method was established to determine simultaneously the contents of phthalate plasticizers in coated papers. The relative standard deviation (RSD) of the proposed method was less than 14% while the average spike recoveries varied from 83.6% to 104.1%. The quantification limits (S/N=10) were 0.2, 0.2 and 0.1 mg/kg for DINP, DIDP and DMPP, respectively. The limits of quantification (S/N=10) were all less than 0.05 mg/kg for other phthalate plasticizers. The proposed method was successfully applied to the determination of phthalate plasticizers in coated papers and the results showed that various phthalate plasticizers existed in some commercial coated papers. |
