The performance of Alumina-Iron Oxide nanocomposite as an adsorbent in the removal of Copper has been investigated. The experimental studies reveal that the removal of heavy metal from waste water can be increased within shorter duration when the nanocomposite is coated with a suitable polymer. The adsorptive properties of prepared nanocomposite with and without polymer were evaluated for the removal of copper ions using batch mode adsorption system. Characterization of the prepared nanocomposite using SEM, TEM and XRD analysis was done to check the removal efficiency before and after adsorption. This paper deals with the removal of copper from synthetic waste water using alumina/iron oxide nano composite and the increase in removal efficiency within a short period of time when it is treated with polymer coated alumina Iron/Oxide nanocomposite. The effects of pH, adsorbent dosage and time were investigated for optimum adsorption on the uptake of copper ions and observed 98 % removal. An ideal experimental response design has been carried out using Box Behnken design to evaluate the effect of different parameters in the batch mode study.

The prepared Polypyrrole/Alumina-Iron oxide nanocomposite has showed 100% adsorption capacity in removing Copper ions from synthetic waste water. The nanocomposite was analyzed using SEM, TEM, FTIR, XRD and EDX. Batch mode adsorption studies were done to check the feasibility of prepared nanomaterial. Adsorption efficiency of the nanocomposite was measured using UV visible atomic absorption spectrophotometry and found 100 % at pH 8. Influence of inceptive Copper concentration, adsorbent dosage, time of contact, temperature, time with dosage, time and concentration were also tested to determine the optimum value in the uptake of Copper ions. Langmuir and Freundlich adsorption isotherm studies were analysed to understand the process of heavy metals adsorption and found best fitted to Freundlich Isotherm.
