| Abstract: | The extract component from the varied preparation steps of infrared method determination petroleum hydrocarbons in soil was investigated by gas chromatography-mass spectrometry qualitatively. It was discussed the reason of the high blank value using petroleum ether as extract solvent. Dichloromethane was suggested as the substitution with the low blank value and high precision. |
