Sugarcane Bagasse Biochar With Nanomagnetite: A Novel Composite Heavy Metals Pollutants Removal

In this novel, we developed a modern and efficient adsorbent that may serve as environmental protection and sustainable development for removing some metal ions such as Fe and Zn from aqueous solution. The new adsorbent was synthesized by mixing the sugarcane bassage biochar with nano-magnetite (SCB-BC/Fe3O4) to form nano-composite. High resolution transmission electron microscope (TEM) imaging shows the synthesized nano-composite with 40 nm average diameters. The adsorption kinetic of metals on the nano-composite was discussed, and the equilibrium equation of the metal ions was found following Langmuir isotherm model. The experimental data showed that the synthesized (SCB-BC/Fe3O4) nano-composite can quantitatively remove the metal ions from water by removal efficiencies of 90% and 96% for Fe and Zn respectively. It can be concluded that the synthesized adsorbent can be used for removal of heavy metals from water and/or wastewater as one of the treatment stages in treatment plants.
