Serial-based chromatographic methods

In recent years, a new class of ILs based on tricaprylammonium chloride (Ali-quat 336) has been investigated. By a simple replacement of the chloride anion, several new ILs have been generated and tested for their applicability, for instance, as extracting agents for heavy metals [641]. However, difficulties arise in the course of the analysis of Aliquat-based ILs as Aliquat 336 is a mixture of quaternary ammonium cations with different alkyl chain lengths rather than a well-defined pure compound. This property makes the quantification of the Aliquat cation and hence all of its products more comphcated. On the other hand, ILs based on quaternary phosphonium cations are already in use for a varietjr of applications. So far, no apphcable LC characterization and/or purity determination of these two classes of ILs was mentioned in literature. In 2008, Stojanovic et al. [642] introduced a reversed-phase liquid chromatographic method with serially coupled diode array detection (DAD) and charged aerosol detection for... [Pg.1383]
