摘要
电解法制备了Ag/AgCl参比电极,并用电子探针分析了其形貌及成分,跟踪了电极在3.5%NaCl溶液中的电位稳定性及长期极差变化,研究了电极对Cl-和温度的响应,并采用恒电流极化的方式测量了其抗极化性能.结果表明,所制备的Ag/AgCl参比电极在3.5%NaCl中稳定性、准确性良好,长期极差变化小,对Cl-响应性好,温度系数小,不易极化,可尝试作为高精度测量装置的敏感元件使用.
A silver- silver chloride reference probe has been made by electrolytic method and its structure and ingredient is characterized with EPMA. A series of its performances are studied. The results show that the silver - silver chloride reference probe has good properties such as stability and precision in 3.5% NaCl, the little potential difference between two probes in long term, the response property to temperature and the concentration of Cl^- ,anti polarization. Thus the probe studied probably can be used as sensor in the precision instrument of electrochemical measurement.
