Abstract: | A sensor is proposed for the direct potentiometric determination of dimethylbenzylammonium in acid and neutral aqueous solutions.
The sensor membrane is made of a polymeric composition on the basis of polyvinylchloride containing an ion associate and a
solvent as a plasticizer. Salts of the tetraphenylborate anion and its derivatives served as ionophores. Basic electroanalytical
parameters of the developed potentiometric sensors are studied and the pH range of their possible application is determined.
The developed sensor is used as a reference electrode in the potentiometric titration of dimethylbenzylammonium with tetraphenylborate
anions. |
