摘要

The present study was conducted in order to investigate the feasibility and reliability of chemically activated Pongamia pinnata leaf carbon for the removal of copper (II) ions in the aqueous solution. Effect of parameter like pH, adsorbent dose, contact time, temperature and initial metal ion concentration were also determined. The optimum conditions obtained were 30 min contact time, 1.0g adsorbent dose, 40 °C, 0.1M Cu and pH 6 for copper removal. The maximum Cu adsorption capacity was found to be 84.9% on using activated pongamia leaf derived carbon. The adsorption process of copper (II) is tested with Langmuir and Freundlich adsorption isotherm models. The results revealed that copper is considerably adsorbed on pongamia leaf derived carbon and it could be economic method for the removal of copper from aqueous solutions. Moreover this study gives a value added utilization of biomass to remove Cu from waste water.
