The chitosan cation membrane was prepared by crosslinked 2% and doped with 1% H_(2)SO_(4).The products were marked as MCS.The physical properties and the ion exchange capacity of MCS were studied.Compared to the non-modified membrane,it was found that chemical modifications contributed to improving ion exchange capacity from 0.25 to 2.09 meq/g.Results was also suggested that the MCS can be used as a separator when producing sodium ferrate flocculent using electrochemical process.
