ABSTRACT

Nanomaterials have continually gained attention due to their unique physical and chemical properties, wide range of applications in various areas, and low cost of production. Iron oxide nanoparticles, having a large surface area and paramagnetic property, can be an effective adsorbent for the removal of toxic contaminants and heavy metals in wastewater. With the growing concern about the environment, green synthesis of iron oxide nanoparticles through microwave irradiation has been preferred. In the present study, the iron oxide nanoparticles were green synthesized by microwave irradiation using phenolic compounds extracted from Ananas comosus peels as the capping agent. Field Emission Scanning Electron Microscopy (FESEM) revealed that iron oxide nanoparticles were found to be in the range of 51.26 to 94.43 nanometers in diameter, had a mean surface area of 16,371.68 square nanometers, and had an average size of 71.49 nm. The nanoparticles, which were intense dark brown to black, with a paramagnetic property, were identified to be quasi spherical, and were insoluble in water. In conclusion, these results indicate that green-synthesis of iron oxide nanoparticles using Ananas comosus peel extract with microwave assistance is possible.
