Abstract

Owing to the limitations of conventional synthesis methods for iron nanoparticles and its wide range of environmental applications, there is a need to develop green synthesis protocols by exploring newer biological resources. In this study, for the first time, Turmeric (AmaranthusspinosusL.) leaves were used to synthesize iron oxide nanoparticles by calcination (FeNPs). As prepared nanoparticles were compared for their efficiency to treat domestic wastewater in terms of orthophosphate (PO4), Chemical Oxygen Demand (COD) and Escherichia coli (E. coli) removal. FeNPs(90%, 92% and 95% respectively) in 24 hours. FeNPs exhibited superior antimicrobial activity inhibited E. coli.
