SYNTHESIS OF MgO, ZnO AND Al2O3 BY SOLID AND SOLUTION COMBUSTION PROCESSES AND STUDY OF THEIR PERFORMANCES IN Co2+ UPTAKE
The study discusses the effect of magnesium, zinc and aluminum oxides prepared by the solid and solution-combustion process. The powders were synthesized by using different urea to metal nitrates ratio and different water concentrations in the solutions. They were characterized by X-ray diffraction,...

| description | The study discusses the effect of magnesium, zinc and aluminum oxides prepared by the solid and solution-combustion process. The powders were synthesized by using different urea to metal nitrates ratio and different water concentrations in the solutions. They were characterized by X-ray diffraction, BET surface area and their performance in Co2+ uptake from aqueous solutions was studied. Results showed that water addition up to a certain limit during the solution combustion method modified the textural properties of the different oxides and that powders obtained by this process have interesting properties, increase the capacity to uptake Co2+ present in water, and increase the surface area of the materials. It was also found that further increments of water in the solutions decreased the Co2+ uptake capacity of the obtained solids. Results with Co2+ ions indicate that they are readily related to the solids prepared by solution combustion processes. It was found that that solution combustion favors cobalt uptake, depending on the amount of water used in the solution. |
