Iron nickel oxide is used as an adsorbent to remove hexavalent chromium ions present in the waste water by co-sedimentation method. It is also employed as an additive in membrane (i.e. polyvinylchloride/styrene-butadiene-rubber blend heterogeneous cation exchange membrane) fabrication, thereby increasing the permeability for bivalent ions compared to the monovalent type.
