Abstract
The transport and removal characteristics of cobalt ions were investigated in a continuous electrodeionization with cation exchange textile (CEDI-CET). It was shown that the removal properties of cobalt ions are strongly dependent on the operating parameters such as temperature, flow velocity, and the solution pH. The transport and removal of cobalt ions was mainly related to the sorption on the surface and the convection and electro-migration through the ion exchange medium. In this study, the CEDI-CET showed good process performance for the removal of metal ions compared with the conventional CEDI with resins.
