Abstract:In this study the application of a novel nano-material composite was investigated in two microextraction techniques of solid phase microextraction and needle trap device in a variety of sampling conditions. The optimum sampling temperature and relative humidity were 10 °C and 20%, respectively for both techniques with two sorbent of graphene/silica composite and polydimethyl siloxane. The two microextraction techniques with the proposed sorbent showed recovery of 95.2% and 94.6% after 7 days. For needle trap device the optimums desorption time and temperature were 3 min at 290 °C and for SPME these measures were 1 and 1.5 min at 240-250 °C for the graphene/silica composite and polydimethyl siloxane, respectively. The relative standard division obtained in inter and intra-techniques comparative studies were 3.3-14.3% and 5.1-25.4% respectively. For four samplers the limit of detection ranged from 0.021-0.25 ng/mL and the limit of quantitation from 0.08-0.75 ng/mL. The results show that graphene/silica composite is an appropriate extraction media for both techniques. Combining an appropriate sorbent with microextraction techniques, and using these in conjunction with a sensitive analytical instrument can introduce a strong method for sampling and analysis of occupational and environmental pollutants in air
