Resumen:
A highly sensitive spectrofluorimetric method has been developed for the determination of 2-ethylhexylnitrate in diesel fuel. Usually, this compound is used as an additive in order to improve cetane number.The analytical method consists in building the chemometric model as a first step. Then, it is possible toquantify the analyte with only recording a single excitation?emission fluorescence spectrum (EEF),whose data are introduced in the chemometric model above mentioned. Another important characteristicof this method is that the fuel sample was used without any pre-treatment for EEF.This work provides an interest improvement to fluorescence techniques using the rapid and easilyapplicable EEF approach to analyze such complex matrices. Exploding EEF was the key to a successfuldetermination, obtaining a detection limit of 0.00434% (v/v) and a limit of quantification of 0.01446%(v/v).
