| Abstract: | A new neutral carrier N,N-dioctyl nicotinic amide (DONA) is synthesized for the preparation of polyvinyl chloride membrane pH electrode, the electrode has excellent potential response in low pH range. In addition, the linear pH response range, potentiometric selectivity, stability, reproducibility and resistance of the electrode are investigated. The electrode has been applied to the determination of ionization constant for hydrofluoric acid with satisfactory results. |
