Ordered Mesopore Channels of SBA-15 for Contaminant Adsorption: Characterization, Kinetic, Equilibrium, and Thermodynamic Studies.

ABSTRACT: SBA-15 is used in various processes, including adsorption, due to its textural properties, mesoporous channels, and silanol groups on the surface. These characteristics make it a promising material for the adsorption of emerging contaminants. This work evaluated the potential use of SBA-15 for the adsorption of bisphenol A (BPA), ciprofloxacin (CIP), and losartan (LS). This study showed that the material has highly ordered mesoporous channels and silanol groups on the surface, which influenced the affinity tests. SBA-15 exhibited the highest adsorption capacity (0.1317 mmol g^-1) and removal percentage (60%) for CIP among the contaminants assessed. The adsorption mechanism was elucidated, revealing different interactions for each molecule. The kinetic curves for CIP adsorption in
