【 摘 要 】

Total spectrofluorimetryassociated to Principal Components Analysis (PCA) were used to classify intodifferent groups the samples of diesel oil, biodiesel, vegetal oil and residualoil, as well as, to identify addition of non-transesterified residual vegetableoil, instead of biodiesel, to the diesel oil. Using this method, the samplesof diesel oil, mixtures of biodiesel in diesel and mixtures of residual oilin diesel were separated into well-defined groups.
