Abstract :
An analysis method was established by using GC to detect the adipic acid in the air and water of working place. The adipic acid in the air is adsorbed by 0.01mol/L NaOH, soured by 0.05mol/L HCl. The adipic acid in the water is soured by 0.05mol/L HCl. Then the adipic acid is extracted by the ethyl acetate. After derivatization of hexamethyl disilazane(HMDS), the target thing can be detected by GC-FID. The linear range of this method is between 2-100μg/mL, the limit of detection is 7μg/m3 and 1μg/L respectively. The sensitivity and precision meet the analysis requirements.
