Abstract
The article aims to optimize the gas chromatography-mass spectrometry(GC-MS)uhich is used to determine the content of diacetone alcohol in water.Under alkaline and acidic conditions,the water sample is extracted with dichloromethane for analysis and determination.The chromatographic column is Rtx-5MS capillary column(30 m×0.25 mm×0.25 μm),and the stationary phase is 5％phenyl-methylpolysiloxane.The results show that diacetone alcohol exhibits a good linear relationship within the concentration range of 1.5～30 μg/mL,the detection limit is 0.09 μg/L,the rate of recovery is 61.2％～101％,and the relative standard deviation(SRSD)is 2.3％～5.4％.It is indicated that this method is accurate and reliable,and can be used for the detection of diacetone alcohol and ethylene glycol ether acetate in water quality.关键词
