Abstract
An efficient, cost effective and eco-friendly approach has been developed for the synthesis of Fe3O4 magnetic nanorods (MNRs) using aqueous extract of Pomegranate leaves (PG). The synthesized PG-Fe3O4 MNRs were characterized by using different microscopic and spectroscopic techniques. The synthesized PG-Fe3O4 MNRs confirmed by Raman scattering and X-ray photoelectron spectroscopy reveal that PG-Fe3O4 MNRs are well dispersed with uniform size (45–60nm) and exhibits high specific surface area of 14.6m2g−1 calculated using BET adsorption-desorption method. The magnetic behavior of PG-Fe3O4 nanorods was studied using vibrational sample magnetometer (VSM) at 300K, and the results obtained shows enhanced magnetic properties of saturation magnetization (Ms, ~59.0emu/g), remnant magnetization (Mr, ~15.5emu/g) and coercivity (Hc, 220Oe). Furthermore, we also reported the use of the synthesized PG-Fe3O4MNRs as an adsorbent to dispose of the Congo red (CR) containing waste water, which exhibited more favorable adsorptive properties as compared to the bulk-metal oxides with low surface area.
