| 中文摘要: |
| 利用2, 4-二硝基苯肼(DNPH)固相萃取在线吸附衍生高效液相色谱-二极管阵列 (HPLC PDA) 测定环境空气中的22种羰基化合物，通过试验优化条件，使方法在6.00 μg/L～1 800 μg/L范围内线性良好，方法检出限为0.025 μg/m3～0.091 μg/m3，加标回收率为93.2%～108%，平行样相对标准偏差<10%。 |
| 英文摘要: |
| An analytical method for the simultaneous determination of 22 carbonyl compounds was developed using on line derivatization 2,4 Dinitrophenylhydrazine (DNPH) solid phase extraction combined with HPLC PDA. The method showed good linearity between 6.00 μg/L～1 800 μg/L (linear correlation coefficient R2 > 0.999). The limits of detection (LOD) ranged from 0.025 μg/m3 to 0.091 μg/m3 and the limits of quantification (LOQ) ranged from 0.10 μg/m3 to 0.36 μg/m3 .The spiked recoveries ranged from 93.2% to 108%, the RSD was less than 10%. |
