    • Disclosed herein is a surface renewable iridium oxide-glass or ceramic composite hydrogen ion electrode and, more particularly, a surface renewable iridium oxide-glass or ceramic composite hydrogen ion electrode, which has a long life due to its excellent physical strength, pH dependency approximate to a theoretical value (59 mV/pH unit), and high surface renewability, and a method of manufacturing the same. The iridium oxide composite hydrogen ion electrode according to the present invention is effective in that, when the electrode is contaminated or inactivated, the surface of the electrode can be regenerated through a simple grinding process because the electrode has high surface renewability, unlike conventional electrodes. The iridium oxide composite electrode according to the present invention can be usefully used in a water-quality monitoring system for monitoring the hydrogen ion concentration of a solution for a long period, an online pH measurement system, and pH measurement for samples, which causes serious contamination of the surface of a sensor.
    • 本文公开了一种表面可再生的氧化铱玻璃或陶瓷复合氢离子电极,更具体地说,是由于其优异的物理强度,pH依赖性近似而具有长寿命的表面可再生氧化铱玻璃或陶瓷复合氢离子电极 达到理论值(59mV / pH单位)和高表面可再生性,以及其制造方法。 根据本发明的氧化铱复合氢离子电极是有效的,因为当电极被污染或不活化时,与常规电极不同,电极的表面可以通过简单的研磨工艺再生,因为电极具有高表面可更新性。 根据本发明的氧化铱复合电极可以有效地用于长时间监测溶液的氢离子浓度,在线pH测量系统和样品的pH测量的水质监测系统,这导致严重的 传感器表面污染。
