Abstract

The anatase TiO2 nanoparticles were synthesized by the reduction of titanium isopropoxide at pH 4.5. The surface area, pore size and pore volume were found to be 156.9 m2/g, 18.23 Å and 0.071 cm3/g respectively. The crystallite size calculated by Debye Sherrer’s equation was found 8.1 nm. The percent purity and the composition were studied by energy dispersive X-rays spectroscopy. The point of zero charge has been calculated from salt addition method. The point of zero charge (PZC) was calculated by salt addition method. The PZC was found to shift to higher values by increasing the concentration of background electrolyte. Batch adsorption technique has been employed for the sorption of Cd2+ ions. The adsorption data was found well fitted to Langmuir model. It was observed that the exchange of surface H+ with Cd2+ is greatly affected with temperature. A set of equations was applied to determine the possible adsorption mechanism of Cd2+ ions onto TiO2 surface.
