摘要 采用袋子法收集儿童安全座椅中挥发性有机物,以热脱附-气相色谱质谱联用和高效液相色谱法测定苯、甲苯、乙苯、二甲苯、苯乙烯、甲醛、乙醛和丙烯醛。苯系物方法检测限0.005 μg/管,醛类物方法检出限0.02 μg/管。苯系物在10~1 000 ng/管的线性范围内线性相关系数R2≥0.999 1,醛类物在0.010~0.1 μg/mL线性范围内R2≥0.999 4。8种特定挥发性有机物的加标回收率90.2%~107.1%,相对标准偏差≤4.2%。进行不同品牌和价位的儿童安全座椅测试,结果显示,该方法快速、准确,可广泛用于产品中特定有害挥发性有机物的日常检测和产品质量管控。

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.
Key words:  vehicle-use child safety seats    certain harmful volatile organic compounds    thermal-desorption gas chromatography-mass spectrometry and liquid chromatography    bag method.
