Özet

Fourier transform infrared (FT-IR) investigation of Oltu-stone (natural carbon black) and jet revealed several differences between these carbonaceous materials. The band peaking at about 1000cm(-1) is the first important difference: while the band in the jet spectra appears as one sharp peak at about 1001cm(-1), the similar band in the Oltu-stone spectra is shifted to about 1026cm(-1) with a broad shoulder toward high frequency. Even though the assignment of the shifted band is at present controversial, it may be attributed to carbon-oxygen stretching mode. Second, the doublet bands at about 2912 and 2843cm(-1) are much more intense in the jet spectra then in the Oltu-stone spectra. They are confidently attributed to aliphatic C-H stretching mode. Finally, the broad water band on setting at about 3750cm(-1) is maturated in Oltu-stone, and it is much more evident than in that of jet. Therefore, FT-IR appears as a favorable identification method for these kinds of carbonaceous materials.
