Description/Abstract

The adsorption of dye molecules from aqueous solution onto the surface of titanate nanotubes (which have been synthesized by an alkaline hydrothermal treatment) has been studied. The ionic charge on the dye molecules was found to affect their ability to adsorb onto the titanate nanotube surface. In case of (cationic) methylene blue, the adsorption was favourable on the negatively charged surface of titanate nanotubes rather than on positively charged P25 TiO2 nanoparticles. In case of (anionic) eriochrome black T dye, the opposite trend was found. The dynamics of dye adsorption and the effect of pH on the adsorption capacity are considered.
