The extracted TPH from the sandy soil was analyzed by FTIR and
GC to monitor the changes in the composition of the TPH qualitatively.
For GC analysis the extracted TPH from the soil sample was
diluted with chloroform and 2 microliter of the resulting solution
was injected to the GC. The temperature of injector and detector
were 250 C and 200 C, respectively. The temperature of the column
was 100 C initially, and increased by the rate of 15 C/min to
300 C. The column was capillary Varian CP-Sil5CB
30 m 0.32 mm 0.10 mm e CP8740. Nitrogen was the carrier
gas. For FTIR analysis the extracted oil from the soil was made into
pellets using KBr in the ratio of 100:1(100 mg KBr and 1 mg sample),
and spectra were taken in the range of 500e4000 cm1.
