Abstract

ABSTRACTOne dimensional titanante nano belts (TNBs) were successfully synthesized by hydrothermal method using TiO2 (Anatase) as a precursor material forming nanobelts of width 15–20 nm. The adsorption of fluoride on to TNBs was found to be pH dependent and exhibited maximum fluoride removal at pH 2. The isotherm data fitted well with Langmuir model with maximum monolayer adsorption capacity of 13.84 mg/g, which is the highest among the nanoadsorbents studied except the titanate nanotubes. Adsorption kinetics were well described by Pseudo second order model. Perfect correlation between the surface area of the titanate nanostructures and fluoride adsorption capacities has been established.
