Chromatographic Behaviour of Ionic Liquid Cations in View of Quantitative Structure-Retention Relationship

Popis výsledku v původním jazyce

The availability of ionic liquids (ILs) in wide areas of application often results in the requirement on their determination. The attention is also often focused on the knowledge of hydrophobicity as it plays a key role in the biological effects, in theassessment of environmental risk and in the prediction of the fate of chemicals in the environment and of its influence on retention in RP HPLC. One can get informatik regarding hydrophobicity and retention mechanism if quantitative structure-retention relationships (QSRRs) are identified. The QSRRs were derived for logarithms of retention factors extrapolated to a pure water (or aqueous buffer) eluent, log kw, determined for the pyridinium and imidazolium ionic liquid (IL) cations on two C8 (SupelcosilLC-8-DB, Symmetry C8) and two C18 (ACE 5 C18, Symmetry C18) stationary phases with isocratic elution by a mobile phase consisting of acetonitrile/40mM phosphate buffer.
