Abstract
This study deals with the adsorption properties of bentonite clay after chemical activation of it with sulphuric, hydrochloric and nitric acids. The treated samples are examined using SEM and Fourier Transform Infrared (FTIR) Spectroscopy. The adsorptive capacities of the samples are investigated by using them to adsorb iron (III) from polluted water. The parameters that affect the iron (III) adsorption such as, contact time, pH, initial iron (III) concentration, and temperature, have been investigated and also optimized conditions are determined. Equilibrium isotherm studies are used to evaluate the maximum adsorption capacity of the modified bentonite where, the experimental results show that sulphuric acid has more capacity than hydrochloric and nitric acids (about 30, 23 and 19) mg/g, respectively.The present study aims to investigate the iron (III) adsorption from polluted water by activating the clay materials, via batch kinetics. Equilibrium studies isotherm are used to evaluate the maximum adsorption capacity of the modified bentonite where, the experimental results show that H2SO4 > HCl >HNO3 (about 30, 23 and 19) mg/g, respectively.
