Study of the Ion Transfer of Quaternary Ammonium Ions by SWV

Simple transfer across the water/nitrobenzene interface of three model quaternary ammonium cations: Tetramethylammonium (TMA+), Choline (Ch+) and Tetrabutylammonium (TBA+), was followed by Square Wave Voltammetry (SWV) which constitutes a more sensitive approach to ionic quantification compared to o...
