UV-Vis spectrometric detection of biodiesel/diesel blend adulterations with soybean oil

UV-Vis spectrometric detection of biodiesel/diesel blend adulterations with soybean oil

A method for detecting adulterations of biodiesel/diesel blends (B5) with soybean oil using UV-Vis spectrometry is proposed. The study involves 90 samples comprising B5 blends with and without the addition of soybean oil (0.5 to 2.5% v/v). Suitable discrimination was achieved by using SIMCA (soft independent modeling of class analogy), KNN (K-nearest neighbors), PLS-DA (partial least squares discriminant analysis) and SPA-LDA (linear discriminant analysis with spectral variables selected by the successive projections algorithm) classifiers.
