Novel Adsorbent For Industrial Wastewater Treatment Applications, Ahmed Y. Zakaria, Dalia A. Ali, Islam M. Al-Akraa, Hoda A. Elsawy, Hany A. Elazab Nov 2019

Novel Adsorbent For Industrial Wastewater Treatment Applications, Ahmed Y. Zakaria, Dalia A. Ali, Islam M. Al-Akraa, Hoda A. Elsawy, Hany A. Elazab

Chemical Engineering

In this study, the hydroxyapatite powder is investigated for both of methylene blue and thymol blue in aqueous solution. The physical and chemical properties of the adsorbent were evaluated systematically using the different techniques including Microsoft Excel programming, linear regression model and also the coefficient of determination. Batch adsorption experiments were conducted to determine the effect of contact time, solution pH, initial dye concentrations, and also the adsorbent dosage on adsorption. The adsorption kinetic parameters confirmed the better fitting of pseudo-second order kinetic model for both of methylene blue and thymol blue. The isotherm data of methylene blue and thymol ...


Microwave Assisted Synthesis Of Binary Metallic Oxides For Catalysis Applications, Abdelrahman Mostafa Kamal, Sherif Bahgat, Mohammed Hammam, M. A. Radwan, M. A. Sadek, Hany A. Elazab Nov 2019

Microwave Assisted Synthesis Of Binary Metallic Oxides For Catalysis Applications, Abdelrahman Mostafa Kamal, Sherif Bahgat, Mohammed Hammam, M. A. Radwan, M. A. Sadek, Hany A. Elazab

Chemical Engineering

Herein, versatile, and reproducible method to prepare binary metal oxides via microwave assisted synthesis. Catalysts are substances that basically speeds up chemical reactions. Ideally, bonds are formed between the catalysts and the reactants. Also, catalysts permits formation of products from the reactants. These formed products, splits off the catalyst without affecting or changing it. Catalytic kinetics studies the correlate chemical reaction rate with some properties of reactants and/or products for instance; temperature, concentration and pressure. The aim of the project is to prepare pure and bi-metal iron based catalyst by co-precipitation method and to characterize the prepared sample using ...


Hydrothermal Preparation Of Palladium Supported On Magnetite For Catalysis Applications, Hany A. Elazab, S. A. Hassan, M. A. Radwan, M. A. Sadek Oct 2019

Hydrothermal Preparation Of Palladium Supported On Magnetite For Catalysis Applications, Hany A. Elazab, S. A. Hassan, M. A. Radwan, M. A. Sadek

Chemical Engineering

Herein, versatile, and reproducible method to prepare Pd/Fe3O4 via hydrothermal synthesis. The vital role of this catalyst is in its potential use in CO oxidation catalysis. The Pd/Fe3O4 shows a distinctive activity. TEM images confirmed that Pd nanoparticles of 8-12 nm have a well dispersion on the surface of magnetite (Fe3O4). Moreover, the prepared catalyst is recycled with remarkable catalytic activity. This outstanding activity is mainly a direct result of the strong metal-support interaction. The defect sites in the reduced iron oxide act as nucleation centers that enable anchoring of Pd nanoparticles leading to prevention of agglomeration.
