Fe3O4/kaolin magnetic nano-composites were prepared by chemical co-precipitation method. The nano-composites were
characterized using various instrumental techniques including X-ray diffraction (XRD), Fourier transform infrared
spectroscopy (FTIR), Scanning Electron Microscopy (Sem), Transmission Electron Microscopy Analysis (Tem), Vibrating
SampleMagnetometer (VSM) andN2 adsorption -desorptionmethod.The preparednano-compositeswere tested and evaluated
as an adsorbent in the removal of the anionic C.I Direct Red 23 dye. The effect of contact time, initial dye concentration,
adsorbent dose, temperature and initial pH of the solution on the adsorption process was studied. The experimental data was
modeled by using different isotherms and the results showed that linearized Langmuir isotherm is applicable to the process
demonstrating a favorable process. Kinetic models were tested and the obtained results fitted best the pseudo-second order
model. The calculation of thermodynamic potential functions such as the changes in enthalpy, entropy, and Gibbs’ free energy
showed that the adsorption is a spontaneous process with an endothermic heat effect and entropy production.
Biography
A Magdy has received his Master of Science degree with honors in Chemical Engineering from Alexandria University, Egypt. He has his expertise in advanced
techniques for water and wastewater treatment. His background was reinforced with his academic career in the Chemical Engineering Department at Alexandria
University. In 2012, he was appointed as a Teaching Assistant at the Arab Academy for Science and Technology. His thesis focused on the discovery of new
materials used for the adsorption of undesired pollutants present in wastewater. His present research is based on the utilization of cheap, readily available kaolin
clay and the extraordinary characteristics of nano iron oxide particles to produce a novel composite which may be applied in the treatment of polluted wastewater
that has threatening effect on human health and aquatic life.
