Determination of Adulterants in Diesel by Multivariate Calibration Associated With LED Spectrofluorimetry

Abstract

In this paper, multivariate calibration models have been developed for determination of common adulterants (kerosene, turpentine and residual oil from fried foods) added to diesel. The samples were analyzed by LED spectrofluorimetry and the multivariate calibration models were developed by Partial Least Squares (PLS). The proposal is suggested as an analytical methodology of low-cost, fast and non-destructive able to quantify the presence of contaminants in the diesel. The results showed that adulterants concentrations were adequately reproduced by the fluorescence spectral data.

Employing artificial neural networks and fluorescence spectrum for food vegetable oils identification

“…FS between 350 and 1050 nm may be obtained using this apparatus. This apparatus was patented in 2012 and is listed in the QUIMIS catalog as Q-798FIL (Meira et al, 2014(Meira et al, , 2015Tomazzoni et al, 2014). Figure 1 excitation light.…”

Nanofotónica en el análisis de biocombustibles

“…Con este artículo queda en evidencia que una herramienta nanofotónica puede ser una solución complementaria al reto global para la determinación del contenido porcentual de biodiésel en diésel. Es aquí donde las técnicas basadas en la interacción de la luz con la materia son de gran utilidad [7][8][9][10][11].…”
