Abstract
Abstract
Heavy metals are principal concomitant pollutants in industrial wastewaters, posing a serious threat to public health and the environment. Herein, we develop a novel strategy to produce a new nanocomposite formed from corn cobs (CCs) and magnetite as a nanomaterial for the simultaneous removal of Fe+2 and Ni+2. The as-prepared nanocomposite was systematically characterized by x-ray diffraction, field emission scanning electron microscopy, mapping, energy-dispersive x-ray spectroscopy, high-resolution transmission electron microscopy, selected area electron diffraction, zeta size, and zeta potential. Compared to the CCs and Fe3O4, the nanocomposite showed better adsorption performance. The maximum adsorption efficiency of the CC, Fe3O4, and the nanocomposite was calculated by atomic analysis to be around 91.84%, 91.28%, and 98.51%, respectively, under the same conditions. This study indicates that the nanocomposite could be a favorable biomass-derived adsorbent for the simultaneous removal of heavy metals.
