| Résumé : | In this paper, a new approach based on the principal component analysis technique (PCA) and UV spectroscopy was applied to the determination of low concentrations of 1-ethyl-3-methylimidazolium ethylsulfate ionic liquid ([Emim][EtSO4]) and toluene in aqueous solutions. By optimizing 10 parameters, the integrated PCA/UV spectroscopy system is able to predict [Emim][EtSO4] and toluene concentrations with a mean predictive error of 2.6% without any previous phenomenological knowledge. |
