Abstract

This project assembles in a concerted manner a number of fundamental studies to improve our ability to manipulate solute mobility for optimization purposes in capillary electrophoresis. A large number of compounds of clinical, forense, pharmaceutical, environmental and food science importance is under consideration comprising homologues series (alkylphenones, alkylphenylketones, halophenols, alkylbenzenes, halobenzenes, benzylamines, crown ethers and alkanes) and functional series (phenolic compounds such as flavonoids, phenolic acids, phenols, etc, terpenes, pesticides, steroids, drugs of abuse, carboxylic acids, amino acids, aliphatic and aromatic amines, food dyes, fatty acids, polycyclic aromatic hydrocarbon, aldehyde and ketones. As a direct outcome, a mobility database (ca. 500 compounds) that might aid solute identification in complex sample matrices will be built using distinct electrolyte systems. For selected classes of solutes, the project comprises studies involving the establishment of solvent effects on acid-base equilibria, cyclodextrin complexation as well as solute-micelle interactions. In addition, the key intermolecular interactions governing solute-surfactant association in pre- and post-micellization regions will be inspected. And finally, micelle solubilization compartments will be probed by quantitative structure retention relationships (QSRR) and molecular dynamics. (AU)
