Two samples of γ–mesoporous alumina (0.3M/m-Al₂O₃ and 0.5M/m-Al₂O₃) were prepared using the microemulsion method, with aluminium sulphate serving as the alumina precursor. The raw materials for microemulsion are sodium dodecyl sulphate (SDS) as the surfactant, 1-butanol as a cosurfactant, and n-hexanol as the oil phase. Scanning Electron Microscopy (SEM), BET surface area, BJH porosity of the samples, and their N2 adsorption-desorption isotherms at 77 K. The X-ray diffraction (XRD) and AFM techniques were used to characterize these samples. The results show that the two samples have identical phase structures and perfect indexing to the γ-Al₂O₃; the 0.3M/m-Al₂O₃ sample has a larger surface area, 229.18 m² g^-1, pore diameter, 5.59 nm, and pore volume, 0.32 cm³.g^-1, than the 0.5M/m-Al²O³ sample. The morphology of the two samples was small spherical particles aggregated in spherical agglomerates, but the 0.3M/m-Al₂O₃ sample displayed smaller particles than the 0.5M/m-Al₂O₃ sample; the percentage of aluminium oxide was high, equal to 95.5% and 97.3% by weight for the 0.3M/m-Al₂O₃ and 0.5M/m-Al₂O₃, respectively. As a model, the 0.3M/m-Al₂O₃ sample was used as a carrier for delivering the ciprofloxacin drug. The loading was performed using the impregnation method, while the release was achieved through a dialysis bag with buffer solutions at pH levels of 7.4 and 5.4. The results indicate that the sample can serve as a suitable carrier for the ciprofloxacin drug.
