In the present study, the effect of synthesis variables on the simultaneous removal of Orthophosphate (PO4) and Chemical Oxygen Demand (COD) from domestic sewage by iron oxide nanoparticles was evaluated by Full Factorial Experimental Design. For the first time, magnetic nanoparticles were synthesized using Turmeric (Curcuma longa L.) leaves (TL) as biotemplate by microwave assisted method. From the analysis of variance (ANOVA), the optimum conditions for the preparation of magnetic nanocomposite were found to be 8% plant material, 1 molar FeCl3 solution and 9 hours of contact time. The metal salt concentration and contact time significantly affected PO4 removal capacity of the nanocomposite whereas COD reduction was influenced by plant material percent and interaction effect of all three variables.
