Voltammetric behavior of alkylammonium ion was studied in the absence and in the presence of crown ether in propylene carbonate as solvent. The peak potentials and the peak currents, their dependency on the concentrations, the reversibility of the electrode reactions are described. In the presence of crown ether chemical reaction might be preceeded before the electron-transfer process, the peak potential for the reduction shifts at the negative direction as the concentration of crown ether to the electrolyte solution increases. The addition of crown ether(2OmM 18CR6)to the electrolyte solution made it possible to determine voltammetrically the dialkylammonium ions(Me2NH2+ ;O.6∼0.8mM) in the presence of the monoalkylammonium ions (EtNH3+ ;1.6mM) and the monoalkylammonium ions (EtNH3+ ; 0.5∼2.5mM) in the presence of the dialkylammonium ions(Me2NH2+;O.5mM)
