Selective Quantitative Analysis for Nonvolatile Oils in Polluted Soil by Thin-Layer Chromatography/Flame Ionization Detection

It was a problem that soil organic matter overlapped on quantitative analysis for nonvolatile oils in polluted soil. A selective quantitative analysis for oil using TLC/FID was attempted for the purpose of a properly/quantitative determination of oil only in polluted soil. Soil organic matter as the interfering substance of the analysis were fractionated with the development of TLC. Moreover, the development distance of TLC was extended so as to divide up the measurement with FID in order to improve of the division between the soil organic matter and the oils. Accordingly, the types of soil organic matter separated from the oils, and the influence for the quantitative analysis of oils in polluted soil was successfully reduced.
