The Department of Chemical Engineering discusses a master's thesis on the removal of cationic and anionic dyes used in tissue laboratories using natural minerals such as Iraqi limestone NIL and zeolite molecular sieve ZMS
The Department of Chemical Engineering at the University of Technology discussed the master's thesis tagged.
Natural Mineral Adsorbent for Elimination of Hazardous Pollutants from wastewater
The student's thesis, Asawer Mahdi Sobhi, aimed to investigate the feasibility of obtaining a high removal of dyes using the batch adsorption method for the purpose of removing cationic and anionic dyes represented by methylene blue and yellow dye.
The effect of pH (3-11), dose of adsorbents (0.03-1.5) g, contact time (0-150) minutes, dye concentration (25-200) mg/l was studied, and the adsorption process was studied at different temperatures (298). -328) Kelvin, and the results showed that the amount of dye adsorption increases when the temperature increases, that is, the process is endothermic for (MB) dye, while the adsorption process is exothermic with respect to (EY). The basic thermodynamic functions were calculated from the compressive free energy, entropy and enthalpy, It was concluded that the adsorption process is physical and that there is an increase in the entropy and the process was automatic for the basic dye. The adsorption kinetics was studied and was more suitable with the second-order kinetic adsorption. It was found that the behavior of ZMS was close to NIL and the removal rate for basic dyes was higher than for acidic dyes.
The discussion committee consisted of:
