Determination of di(2-ethyl hexyl) adipate in Nenjiang river water by gas chromatography/mass spectrometry

The Di(2-ethyl hexyl) Adipate(DEHA) in Nenjiang river water 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 0.32μg/L(S/N=3),recoveries were in the range of 90%～ 97%,the RSD were in the range of 4.38%～4.79%.This method was of si mple,speed,accurate which was suitable to the determination of Di(2-ethyl hexyl)Adipate in Waters.
