| Abstract: | The di(2-ethyl hexyl)adipate(DEHA)in polyvinyl chloride plastics was extracted by hexane with ultrasonic generator.The determination of di(2-ethyl hexyl) adipate carried out by gas chromatography /mass with selected ion monitoring(SIM) mode,using external standard method.The detection limit of DEHA was 0.4μg/kg(S/N=3),recoveries were in the range of 90%~95%,the RSD were in the range of 0.12%~0.28%.This method was of simple,speed,accurate which was suitable to the determination of di(2-ethyl hexyl) adipate in polyvinyl chloride plastics materials and products. |
| Keywords: | di(2-ethyl hexyl)adipate(DEHA) polyvinyl chloride plastics(PVC) gas chromatography/mass |
