Abstract.
The process of extraction of amino acids at 298 K through hydrophobic liquid membranes, performed with reversal micelles of aerosol OT (AOT) in chloroform, was studied by using bulk liquid membrane (BLM) method and UV-Vis spectroscopy. All transport rates were calculated by using the OLS method, and the results are discussed in terms of hydrophobicity, chemical potential gradient and electrostratic interactions. In all cases, the compounds show overlapped UV-Vis spectra and therefore chemometric methods were applied to solve a practical problem, in this study of the simultaneous transport of chemical species through liquid membranes.
