In this book lepidocrocite and goethite nano structures are studied for their application in lead removal from aqueous solutions. Lepidocrocite and goethite nano particles were synthesized and characterized. Subsequently their performance in lead sorption was examined. Maximum adsorption capacity of lepidocrocite and goethite for lead adsorption via equilibrium studies was investigated. Furthermore capability of lepidocrocite and goethite in lead removal efficiency was compared and the more efficient adsorbent was employed to fabricate chitosan nano composite. Adsorption performance of...
