Abstract  

In order to enhance the stability of two-electrode system detecting instrument, active carbon (AC) electrode with large surface area had been used as all-solid-state counter electrode in novel detecting instrument. After investigating the super capacitance property and potential stability of AC electrode, it had been served as counter electrode, together with Pt and glassy carbon working electrode to form a two-electrode water quality detecting instrument for hydrogen peroxide and lead ion determination, respectively. The detection results indicate that, the sensitivity, detection limit and detection range of this detecting instrument are all reach the detecting performance of conventional three-electrode system. Active carbon is of advantages as potential stable, chemical inertness, low cost, ease of use and maintenance, which makes the novel two-electrode water quality detecting instrument simpler with a high reliability and a promising application prospect.

两电极体系新型全固态电极特性分析与应用

为提高两电极体系检测仪器的稳定性,采用具有极大比表面积的活性炭电极作为全固态对电极构成新型两电极体系检测仪器,并对该仪器特性进行一系列分析.研究考察活性炭电极的超级电容特性和电极电位稳定性,以铂、玻碳电极为工作电极,新型全固态活性炭电极为对电极,构建两电极体系水质检测仪器,并应用于水体中双氧水与铅离子的检测.结果表明,该检测仪器的灵敏度、检出限、检测范围均取得了与三电极体系类似的检测结果.采用活性炭对电极的固态电极具有电位稳定、化学惰性、价格低、易于小型化、易于使用和维护等优点,使构建的两电极水质检测仪器结构简单、可靠性高,具有较好应用前景.
