Removal and Kinetics of Oxalic Acid Adsorption from Aqueous Waste over Alkali Activated Power Plant Fly Ash


Author(s): M. Dakshene, A. Rani, P.D. Sharma

Abstract: Oxalic acid is a chemical that is commonly used in the production of lubricant component, plasticizers, pharmaceutical, and rubber industries. Effluent emitted from these industries contain this chemical is a major cause of pollution in water system and is hazardous to the living beings. This chemical is reported to cause pain, tearing in eyes, skin irritation etc. Fly ash from coal burning power plant was activated chemically, used as a low cost adsorbent for the removal of oxalic acid, which is a major cause of pollution in water system. The activated fly ash was characterized for mineralogical, physiochemical and morphological properties by XRD, FT-IR and SEM. Results showed that activated fly ash due to increased amorphous property possesses more activity over surface to act as a suitable adsorbent for the removal of acidic waste from individual effluents. The adsorption kinetics is well represented by first order kinetic model.
