铂电极对铜和银非电对离子瞬时响应信号的研究

The Transient Response Signals of Platinum Electrode to Copper?and Silver?

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 signals of platinum electrode to uncoupled ions Cu 2+ or Ag + are measured by active step method. They are signal peak potentials and lg a M 2+ to obey the Nernst equation, and the ion′s Seq effect on the kind of peak has been proved.
