5.3.1.1 Cobalt and Nickel Separation. The separation of cobalt from nickel in aqueous solution has been found to be difficult because of their very similar chemical behavior. Although cobalt and nickel exist as divalent hexahydrated ions in aqueous solution, the rate of water exchange on the cobalt ion is much higher than for nickel.
