用活度阶梯变化法测量了铂电极对Cu2 +、Ag+的瞬时响应信号为单峰类型 ,并且在一定浓度范围呈Nernst关系。进一步证实了平衡时离子交换产物的摩尔分数Seq值对瞬时响应信号类型的影响。
The transient response of platinum electrode to Cu2 + and Ag + was measured by the step-by-step method. The transient response signal of the platinum electrode was monomodal and showed a Nernst relationship at a certain concentration range. The effect of the Seq value of the ion exchange product at equilibrium on the type of transient response signal was further confirmed.
