TL;DR: A pilot scale ion exchange/electrodialysis system was tested on-site at a galvanic plant as discussed by the authors, which operated continuously without the need of maintenance for a period of 3 months and was able to remove nickel to concentrations less than the analysis detection limit of approximately 0.2 ǫm−m−3.

TL;DR: In this article, the removal of nickel ions from a packed bed of ion exchange material under an applied potential is studied, which involves the use of an electrodialysis type cell.

TL;DR: In this paper, the authors describe the continuous removal of nickel ions from a dilute solution using a hybrid ion exchange/electrodialysis process and the ionic state of the bed during the process, and the mass balance of ions in the system.

TL;DR: The removal of nickel ions from a low cross-linked ion exchange resin using an applied electrical potential gradient was studied in this paper, where the potential gradient across a bed of ion exchange particles, in which nickel ions were absorbed, was varied by two methods.

TL;DR: In this article, the removal of nickel ions from dilute solutions using a process that combines an ion exchange bed with electrodialysis has been studied, where the main aspects include: the concentration of nickel ion in the diluate, the voltage over the cell and the current density distribution along the ion-exchange bed.
