Abstract
Nanosized mesoporous materials, Si-MCM-41 and Al-MCM-41, were synthesised and characterised. Dye adsorption on the synthesised mesoporous materials in aqueous solution was tested. It is found that Si-MCM-41 exhibits a reversible adsorption while AlSi-MCM-41 presents an irreversible adsorption. Kinetics of adsorption and desorption of dye follows the pseudo first-order kinetics.
