摘要
测定Ｐｂ（Ⅱ）在Ｎａｆｉｏｎ修饰电极上离子交换富集过程中的离子交换系数及物理扩散系数，提出了该过程中，Ｐｂ（Ⅱ）在Ｎａｆｉｏｎ膜中的浓度分布模型和Ｐｂ（Ⅱ）离子交换与扩散模式．
A determination was made on ion-exchange coefficient and diffusion coefficient of Pb (Ⅱ) over Nafion modified electrodes during the process of ion-exchange concentration. On this basis,the authors put forward a model of Ph(Ⅱ)concentration distribution over Nafion polymer film and a model of Ph(Ⅱ) ion exchange and diffusion during this process.
