Abstract
The ion transfer of acetylcholine (AcH+) ions across the unmodified and phospholipid-modified waterj1,2-
dichloroethane (DCE) interface has been studied by means of square-wave and cyclic voltammetry, as well
as by electrochemical impedance spectroscopy. After being transferred in the organic phase, the AcH+ ions
undergo chemical reactions with the phospholipids. The overall behavior of the experimental system studied
in the presence of phospholipids has been compared with the theoretical results of an ECrev reaction. The
kinetic parameters of the chemical interactions between AcH+ and the phospholipids have been determined
from the voltammetric and impedance measurements. Additional characterization of those interactions has
been made by using the surface tension measurements.
