Recycling of Industrial Solid Wastes: 'Waste' FeIII/CrIII Hydroxide as an Adsorbent for the Removal of Toxic Ions and Dyes from Wastewater

摘要

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