Abstract
This study detected 13 aldehyde and ketone compounds in indoor air and analyzed indoor air contamination,so as to protect the health of residents.An adsorption sampling tube with 2,4-dinitrophenylhydrazine(DNPH)on the surface was used to collect aldehyde and ketone compounds in the ambient air,eluted with acetonitrile to constant volume,and the eluent was analyzed and detected by a high performance liquid chromatography equipped with an ultraviolet detector.When the sampling volume was 0.10 m3,the lowest detectable concentration of 13 aldehyde and ketone compounds was 0.27～0.86 μg/m3,the lower limit of determination was 0.78～3.43 μg/m3,the precision was 0.7%～12.2%,the average spiked recovery was 98.6%～100.9%,and the method correlation coefficient(r2)was 0.9992～0.9999.The method has high accuracy,low detection limit,simple operation,and can be used for the detection of aldehyde and ketone organic pollutants in indoor air in residential places.关键词
