Web10 mei 2016 · Ion Exchange. Because dissolved manganese is in the form of the divalent cation Mn 2+, the process of ion exchange (IX) can be used to remove manganese from water. In this process, a monovalent cation, Na + or H +, is typically released from a cationic ion exchange resin (or media) as Mn 2+ is selectively removed. http://www.reachdevices.com/Protein/ProteinPurification.html
