摘要
介绍了一种自制的参比电极。银丝为工作电极,在盐酸溶液中用循环伏安法制得了银-氯化银电极,它的形貌是由棒状的氯化银和银颗粒构成。其策略是根据铂丝与硬质玻璃的线性热膨胀系数的差异,将铂丝熔融封入硬质毛细管玻璃底部构成饱和银-氯化银电极。该电极具有可靠而准确的电位值,特别适用于现场光谱-电化学实验,也可用于有机电解质体系中的电化学研究。
This paper introduced a novel and micro-saturated silver-silver chloride electrode with micro-passage. The Ag/AgCl (s) was prepared using cyclic voltammetry in an electrolytic cell containing an Ag wire and HCl solution. The morphology of Ag/AgCl (s) is composed of AgCl(s) tubes and Ag particles. On the basis of the different linear thermal expansion coefficients of the hard glass and Pt wire, a Pt wire was sealed in the bottom of a hard capillary glass tube to fabricate the micro-saturated silver-silver chloride electrode with micro-passage. The reference electrode has a reliable and accuracy potential value, which in particular is suitable to the experiments of in-situ spectroelectrochemistry and also to the electrochemistry experiments of organic electrolytes.
