- Abstract
The coated iron nanoparticles (CA-ELE-Fe NPs) were synthesized using eucalyptus leaves extract and calcium alginate (CA). The results showed that 74.7% of diesel was removed using CA-ELE-Fe and H2O2, while only 13.19% and 10.15% of diesel oil were removed by CA-ELE-Fe and H2O2 after 240 min, respectively, which demonstrated that CA-ELE-Fe NPs exhibit a good adsorption ability and act as excellent Fenton-like catalyst. Scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FT-TR) confirmed the successful synthesis of iron nanoparticles and indicated the changes in CA-ELE-Fe NPs before and after reaction with oil. Various materials were applied to treat practical oil wastewater, which showed that 80.24%, 82.47% and 44.36% of diesel was removed by CA-ELE-Fe NPs, green synthetic nano particles (ELE-Fe NPs) and zero-valent iron nanoparticles (nZVI), respectively. Meanwhile, diesel removal efficiency reached 67.46% by used CA-ELE-Fe NPs, because the coating of calcium alginate reduced the iron nanoparticles releasing to liquid.
