DEVELOPMENT OF A DISCRIMINATION METHOD OF BOHAI SEA SIMULATED OIL SPILLS BASED ON STABLE CHARACTERISTIC PEAK RATIO OF HPLC

The effect of weathering outdoors on the distribution of HPLC characteristic peaks is examined,and a methodology using HPLC stable characteristic peak ratios combined with several statistical data correlation analysis methods is developed for oil differentiation,including clustering analysis and Student′s t-test method.The origins of simulated oil spills can be speculated preliminarily through the method using HPLC stable characteristic peaks ratios combined with clustering analysis.Further,the oil spills and suspected sources can be successfully identified via using HPLC stable characteristic peaks ratios combined with Student′s t-test method.The methodology using reverse phase HPLC stable characteristic peaks ratios combined with multi-statistical analysis is expected to be a powerful tool for the discrimination of oil spill discrimination.
