摘要
本文研究了低浓度的重金属离子Zn^(2+)、Ni^(2+)、Cu^(2+)及H^+在浓度差和电场作用下通过阳离子交换膜的迁移行为,以表观迁移速率(j)表征不同离子在各种条件下的迁移特性.文中还以四对阳膜和阴膜组成的微型电渗析器进行了从稀溶液中浓缩Cu^(2+)的试验,效果较好.
The transport behaviors of some heavy metal ions, such as Zn2 + , Ni2+,Cu2 + and H+ through cation exchange membrane driven by concentrationand electric potential difference were studied. The immigration rates ( J )of ions in different conditions were obtained. Good results of concentration Cu2+ from dilute solutions with four pairs of ion exchange membranes in an electrodialyser were received .
