交换电流(i_0)是描述电极过程可逆程度的基本动力学参数之一,它反映了体系固有的动力学特征。测定交换电流的方法很多,其中示踪原子法灵敏度较高,并可直接测出平衡电位下的交换电流值。本工作对一系列Ag/AgNO_3-NH_3体系的交换电流进行了测定,并对此方法的适用条件进行了分析和验证。方法原理
The exchange current (i_0) is one of the basic kinetic parameters describing the reversibility of the electrode process, which reflects the inherent kinetic characteristics of the system. There are many ways to determine the exchange current, of which the tracer atomic method has higher sensitivity and can directly measure the exchange current value under the equilibrium potential. In this work, the exchange current of a series of Ag / AgNO_3-NH_3 system was measured, and the applicable conditions of this method were analyzed and verified. Methodology
