Title: Characterization of Sugarcane Bagasse Fly Ashfor Use as Heavy Metal Adsorbent
Author: Elbasheer, Ola Elamin Eltaybe
Abstract: To minimize the industrial pollution, advanced wastewater treatment techniques, such as adsorption, are economically and environmentally essential in the removal of heavy metals and organic compounds from industrial wastewater, The objective of this research focuses on the chemical and physical characterization of three samples (SBA1,SBA2 and SBA3) of low cost adsorbent sugarcane bagasse fly ash from Guenied Sugar factory, Chemical characterization was done spectrally, through the examination of X-ray fluorescence and diffraction and Fourier transform infrared spectroscopy.Physical characterization was done by iodine value test, bulk density and particle size distribution.The three asheswereheterogeneous with irregularparticle size distribution, and a prevalence of superficial polar groups (carbonyl, carboxyl, and hydroxyl), chemical composition of the three ashes presented an important inorganic fraction (real ash) with prevalence of silica SiO2 (25.043%, 28.819% and 28.790%) and also presence of oxidized metallic species, such as CaO (17.265%, 20.782 and 20.754%), Fe2O3(8.237%, 10.177% and 10.161%) and Al2O3(3.997%, 4.566%, and 4.562%). Ashes have bulk density (0.482g/ml, 0.648g/ml and 0.568g/ml), and iodine number (103.09mg/g, 97mg/g and 91.2mg/g). The results of each analysis were compared to those of recognized or potential adsorbent materials. Based on their physical and chemical characteristics, ashes could be used as adsorbent for both, inorganic (e.g., heavy metals) compounds and organiccompounds (e.g., dyes, phenols, etc.(
