Study of Removal of Heavy Metal Copper (II) from Aqueous Solutions by Punica Granatum Seed Powder by Adsorption

Authors(1) :-Shobha Borhade

Heavy metals contribute to a variety of adverse health environmental effects due to their acute and chronic exposure through air, water and food chain. Heavy metal toxicity can result indamaged or reduced mental and central nervous function, lower energy levels,and damage to blood composition, lungs, kidneys, liver, and other vital organs.Long-term exposure may result in slowly progressing physical, muscular, andneurological degenerative processes that mimic Alzheimer's disease. Copper is highly toxic due to its non biogegradable and carcinogenic. Punica granatum seed powder use as a natural adsorbent for effective removal of copper (II). The main parameters influence the adsorption of copper (II) as percentage recovery, initial metal concentration, effect of adsorbent dosage, metal ion concentration, effect of time and effect of pH was studied in batch process.The adsorption study were carried out isothermally at different temperatures. Freudlich isotherm and Langmuir isotherm were used to describe the equilibrium data and the result were discussed in details.The kinetic data well described by the pseudo first order kinetic model. The thermodynamic parameters such as standard free energy change, entropy change and enthalpy change were studied for Punica granatum seed powder. This values showed that the adsorption of copper (II) ion on Punica granatum seed powder was a spontaneous and endothermic process. The removal of copper (II) ion from waste water and the techniques will be applicable at low cost.
