Removal of copper (II) from aqueous solution by modified agricultural waste materials

The agricultural waste materials of Glycine max was modified using activating agents such as phosphoric acid. The modified material agricultural waste was used for the removal of copper from aqueous solution. The influence of copper (II) concentration, pH, adsorbent dose and contact time on the removal of copper from aqueous solution was investigated. The experimental data were fitted well by Freundlich isotherm and Langmuir isotherm. The modified agricultural waste has greater potential for copper removal due to cheaper nature and higher uptake. The present study showed that modified agricultural waste materials were capable of removing copper ions from industrial wastewater samples.
