Discussion of a Master’s Thesis
The Department of Chemistry at the College of Education for Pure Sciences discussed the master’s thesis for the student (Ali Abdel Rahim Kazem) entitled (Study of the removal of Celestine Blue B and Basic Fuchsine dyes from their aqueous solutions using CuCo2O4 and CuCo2O4-MgO as adsorbent surfaces), under the supervision of Prof. ), and Professor (Saleh Hadi Kazem). The study aimed to: 1. Preparation of two absorbent surfaces are the two compound spinel type CuCo2O4 and -MgO CuCo2O4 catalysts. 2. Diagnosing the two catalysts using XRD, AFM, FT-IR, and FESEM techniques. 3. The use of the two catalysts in water purification from organic pollutants is represented by the removal of the two dyes Celestine blue (CBB) and the basic fuchsin (BF) by the adsorption process. 4. Studying the optimal conditions for the adsorption process such as equilibrium time, and auxiliary agent dose. 5. Studying the isotherms of the adsorption process and knowing the type of isotherm and its conformity with adsorption models Langmuir, Temkin, Freundlich. 6. Studying thermodynamic functions (ΔG, ΔS, ΔH) and finding out whether the adsorption process is spontaneous or not. As for the most prominent conclusions: 1. The possibility of removing toxic dyes from their aqueous solutions, such as CBB and BF dyes. 2. The removal efficiency of CBB and BF dyes is affected by factors (equilibrium time, dye concentration, adsorbent surface amount). 3. The equilibrium data for the two dyes showed that they agree well with Freundlich isotherms. 4. The results showed that magnesium oxide is a carrier in the adsorbent surface CuCo2O4-MgO spindle type. 5. The results showed the role of MgO in reducing the proportion of the adsorbent surface of the CuCo2O4 spinel compound. The recommendations were: 1. Because of the increase in population and industrial growth, which resulted in an increase in pollution in the world. 2. Study of adsorption of other species on the two composite surfaces CuCo2O4 and CuCo2O4-MgO spell type. 3. Study the ability to remove air pollutants emitted from power plants. 4. Studying the possibility of developing the two composite surfactants of CuCo2O4 and CuCo2O4-MgO-type spinel. After extensive scientific discussion and listening to the student’s defense of his message, his method of research, and his use of sources and references, the thesis was approved with honors. Congratulations to the student, his supervisor, the College of Education for Pure Sciences, and the University of Karbala, and more creativity in the service of our beloved Iraq, and from God Almighty success and payment.
