An experimental study of the tetrafluoroborate ion selective electrode based on PVC matrix membrane containing the quaternary ammonium salt and solvent mediator was described. Among the different quaternary ammonium salts and various solvents tested, triheptyldodeeylammonium (THDDA) tetrafluoroborata-di (ethylhegyl) phthalate (DEHP)-PVC membrane is the most attractive in respect to the electromotive behaviour of the corresponding electrodes. The optimum membrane composition is (w/w) 2% THDDA, 68% DEHP and 30% PVC.
