| Abstract: | The application of the membrane in recovery of some popular arson accelerants such as gasoline, diesel, jet koresene and paint thinner, as well as their fire debris was studied in a laboratory recovery unit. About 68% benzene spiked in the cement could be recovered within 20 rain under 100 ~C. High temperature and vacuum conditions were beneficial to recovering fire accelerants and debris from spiked cements. With the membrane and recovery method, the gasoline, diesel, and paint thinner in the cement were satisfactorily recovered and were then separated and analyzed on GC-FID. The gasoline, diesel, jet koresene and paint thinner spiked in the carpet and cotton, were recovered together with their fire debris by using this membrane, and were analyzed on GC-FID. |
