| Research Abstract |
In the cathode of waste secondary battery, the valuable metals such as Co, Ni and Mn ions were included. The development of selective recovery and separation processes for the each metal from waste battery solution including several valuable metals is especially significant from the viewpoint of industrial or environmental problems. In this study, adsorptive equilibrium and separation characteristic of Co, Ni and Mn ions using the chitosan fiber and the ion-exchange fiber were investigated. Furthermore, continuous separation and recovery process using belt-type ion exchange fiber was developed and adsorptive separations of cobalt were investigated. Using the developed separation and recovery process, the perfect separation of cobalt from waste secondary battery were performed.
