Abstract: A bag method is established to collect volatile organic compounds (VOCs) in vehicle-use child safety seats.Benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde, acetaldehyde and acrolein are detected by means of thermal desorption-gas chromatography-mass spectrometry and high-performance liquid chromatography.The detection limits for BTEX are 0.005 μg per tube, and that for aldehydes are 0.02 μg per tube.In the linear range of 10-1 000 ng per tube, the correlation coefficient R2 for BTEX is not less than 0.999 1.In the linear range of 0.01-0.1 μg·mL-1, the R2 for aldehydes is not less than 0.999 4.The recovery rates of 8 kinds of VOCs are in the range of 90.2%-107.1%, and relative standard deviations are not more than 4.2%.Different brands and prices of vehicle-use child safety seats are chosen for testing by this detection method.The test results show that the method exhibits fast and accurate, and can be widely used in the daily test and product quality control of certain harmful volatile organic compounds in vehicle-use child safety seats.
