Abstract

Objective To establish a GC method for the determination of dimethylformamide and N-N-dimethylacetamide in air of workplaces. Methods The samples were collected by silica gel tube, desorbed by alcohol, determined by GC. Results The linearity range was 0.13-133.3 mg/m3 for DMF(r=0.999 6),0.20-133.3 mg/m3 (r=0.999 5)for DMA(the air volume was 1.5 L). The limit of detection was 0.2 μg/ml for DMF and 0.3 μg/ml for DMA. Collection efficiency was 100% for DMF,99% for DMA. Desorption efficiency was 97% for DMF, 98% for DMA. The penetration capacity was more than 2.5 mg for DMF,more than 2.4 mg for DMA. The samples could be stored for 7 days in a refrigerator at 4 ℃or in room temperature. Conclusion This method is simple, accurate, wider determination range and is applicable to the determine DMF and DMA in air of workplaces.
