| Abstract: | A hydrogen electrode based on an ion neutral carrier, o-hydroxybenzyl-didodecyl-amine （Ⅱ）, has been designed and applied for the determination of pH value in waste water containing fluoride. The PVC membrane pH electrode based on the carrier material has a wide linear response range of pH 2.0-12.5 and a Nernstian response slope of 56.9±0.4 mV/pH （25℃）. Having low resistance, short response time, high selectivity, good repro-ducibility, high stability, and being resistant to hydrofluoric acid and not fragile, the electrode can be well utilized to the determination of pH in waste water samples containing flu-oride. |
