Abstract
In this work the preparation of cobalt spinel CoAl2O4 is described. The technique of colloidal solution destabilization was used as the sol-gel process. The powder obtained from the dried gel was characterized by thermal analysis (thermogravimetric and differential), X-ray diffraction, infrared spectroscopy, and specific surface area measurement. Crystallization of CoAl2O4 spinels occurs at about 400°C. The study of surface properties (surface charge and electrophoretic mobility) of the spinel powder fired at 600°C, in suspension in different electrolyte solutions (10−3 molar ionic strength), shows that the spinel material charge depends on the pH of the solution. The spinel sol was used for the preparation of membrane by the slip-casting method.

The technique of colloidal solution destabilization was used as the sol-gel process. The powder obtained from the dried gel was characterized by thermal analysis (thermogravimetric and differential), X-ray diffraction, infrared spectroscopy, and specific surface area measurement. Crystallization of CoAl2O4 spinels occurs at about 400°C. The study of surface properties (surface charge and electrophoretic mobility) of the spinel powder fired at 600°C, in suspension in different electrolyte solutions (10−3 molar ionic strength), shows that the spinel material charge depends on the pH of the solution. The spinel sol was used for the preparation of membrane by the slip-casting method.</abstract><note>Refereed</note><note type="content">Fig. 1: TGA curve for the dried gel.</note><note type="content">Fig. 2: DTA curve for the dried gel.</note><note type="content">Fig. 3: X-ray patterns of CoAl2O4 spinel fired at different temperatures.</note><note type="content">Fig. 4: Infrared spectra of the spinel powders fired at different temperatures.</note><note type="content">Fig. 5: SEM micrographs of powders fired at 400 and 800°C.</note><note type="content">Fig. 6: Variation of surface charge density vs. pH.</note><note type="content">Fig. 7: Evolution of pHf vs. pHi (pHf = pH at equilibrium, pHi = initial pH).</note><note type="content">Fig. 8: Electrophoretic mobility of CoAl2O4 powder vs. pH.</note><note type="content">Fig. 9: SEM micrograph of CoAl2O4 membrane fired at 450°C.</note><note type="content">Table 1: Specific surface area as a function of firing temperature</note><note type="content">Table 2: Point of zero charge (PZC) for CoAl2O4 powder in different electrolyte solutions</note><note type="content">Table 3: Values of isoelectric point of CoAl2A4 powder, fired at 600°C, in suspension in different electrolyte solutions</note><subject lang="en"><genre>Keywords</genre><topic>A.
