Analysis of arson debris is the foremost challenging task to the forensic investigators. Identification ofthe ignitable liquid residues in the fire debris is one of the prime objectives of forensic quest. This studyevaluates the potential of derivative ultraviolet-visible spectrophotometric methods for the analysisand identification of ignitable liquid residues. In this work, arson was simulated using kerosene as anignitable liquid on various matrices. Derivative UV spectra of kerosene were recorded in their neatstate and compared with those obtained from simulated fire debris samples for the identification anddetection of ignitable liquid residues. It was observed that different burnt substrates did not cause anyinterference. The obtained results indicated that the ignitable liquid absorption capacity of the substratecan play an important role in the extraction and identification of ignitable liquid from fire debris. Theused technique proved to be rapid, easy, reproducible and efficient.
