The Department of Chemistry Discusses a Master’s Thesis on the Study of Removing the Dyes Azure A and Coo Mosie Brilliant Blue G-250 from Their Aqueous Solutions

Discussion of the Master’s Thesis

The Department of Chemistry at the College of Education for Pure Sciences at the University of Kerbala discussed a master’s thesis entitled (Study of removing the dyes Azure A and Coo mosie brilliant blue G-250 from their aqueous solutions using nano-complexed oxides of the spinel type MnFe2O4 and MnFe2O4 -MgO as adsorbent surfaces) by the student (Manal Sami Abdul Redha), under the supervision of Prof. Dr. (Munir Abdul Ali Abbas).
The thesis aimed to prepare two adsorbent surfaces, which are the two adsorbent catalysts of the spinel type, the bare and the loaded, and to use the two adsorbent surfaces in purifying water from organic pollutants represented by removing the dyes Azure A and Coomosie brilliant biue G-250 by the adsorption process because they are considered toxic organic dyes.
The thesis also concluded that toxic dyes can be removed from their aqueous solutions such as Azure A and CBBG-250 dyes using the two adsorbent surfaces with the MnFe2O4 and MnFe2O4-MgO spinel structure by adsorption process. The removal efficiency of the two dyes Azure A and CBBG-250 is affected by factors (equilibrium time, dye concentration, amount of adsorbent surface, acidity function, ionic intensity, temperature). The study recommended that due to the increasing level of pollution in the world, it would be useful to conduct extensive studies on the ability of the two adsorbent surfaces with the MnFe2O4 and MnFe2O4-MgO spinel structure used in the research to many organic and inorganic pollutants found in river water, factory waste, oil refineries and laboratories. The student received an excellent grade.
