Abstract
'Waste' FeIII/CrIII hydroxide, generated from the treatment of CrVI in fertiliser industry effluent, was used as an adsorbent for the removal of toxic ions such as AsIII, HgII, CrIII and PO43–, and dyes such as Rhodamine-B and Procion Orange M2R, from aqueous solutions. The removal was efficient except for Procion Orange.
