| Abstract: | A method for the determination of components in fatty acid in soil samples was established. Fatty acid components in the samples were separated and identified by gas chromatography-mass spectrometry (GC-MS) and each component was quantified by GC with standard solution calibration. The linear correlation coefficients (R2) of the method for each component were 0.9913~0.9999. The detection limits of the method for the components were 0.016~0.038 mg/L. Average recovery of the method was 97.86% with precision of 0.73%~2.57%RSD(n=6). The method has been applied to the quantitative analysis of fatty acid components in soil samples with satisfactory results. |
