铂电极对非电对离子Zn^(2+)、Co^(2+)、Ni^(2+)的瞬时响应信号

Transient Response Signal Mechanism of Platinum Electrode to Uncoupled Ions Zn^(2+), Co^(2+), Ni^(2+)

用活度阶梯变化测量了铂电极对Ｚｎ２＋、Ｃｏ２＋、Ｎｉ２＋的瞬时响应信号．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 response mechanism of platinum electrode to uncoupled ions Zn2+, Co2+ or Ni2+ is studied by the active step method. Nonmonotonic overshoot-type transient signals are analyzed and discussed. Experimental results show that the ion's mole Seq value does have an effect on the type of transient signals.
