One of its applications is in an advanced oxidation process (AOP) called the sono-Fenton process. This study presents the characterization of the nZVI particle by its particle size, scanning electron microscope (SEM) images, transmission electron microscope (TEM) images, X-ray diffraction (XRD), energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS) analysis. Results show that the average size of nZVI is 49 nm and it has two layers. The outer layer (shell) is comprised of iron oxides (i.e. FeO) while the core is elemental iron (Fe). At pH 2, nZVI was found to be a good replacement for iron sulfate (FeSO4) as a ferrous iron (Fe2+) source in the sono-Fenton process. In addition, the removal process of organic pollutants from diluted palm oil mill effluent (POME) was also accelerated by ultrasound, particularly at higher intensity and longer sonication time. Eighty percent (80%) of the chemical oxygen demand (COD) was removed in 2 h instead of 24 h by silent degradation. 2014-06-15T13:18:24Z 2014-06-15T13:18:24Z 2014-03 Article Journal of Environmental Chemical Engineering, vol.2 (1), 2014, pages 1–8 2213-3437 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35521 http://www.sciencedirect.com/science/article/pii/S2213343713002376 10.1016/j.jece.2013.11.021 en Elsevier
