| Abstract | Hydrous titanium dioxide (TiO2 center dot xH(2)O) nanoparticles were synthesized by a low-cost one-step hydrolysis process with aqueous TiCl4 solution. These TiO2 center dot xH(2)O nanoparticles ranged from 3 to 8 nm and formed aggregates with a highly porous structure, resulting in a large surface area and easy removal capability from aqueous environment after the treatment. Their effectiveness on the removal of As(III) (arsenite) from water was investigated in both laboratory and natural water samples. The adsorption capacity on As(III) of these TiO2 center dot xH(2)O nanoparticles reached over 83 mg/g at near neutral pH environment, and over 96 mg/g at pH 9.0. Testing with a As(III) contaminated natural lake water sample confirmed the effectiveness of these TiO2 center dot xH(2)O nanoparticles in removing As(III) from natural water. The high adsorption capacity of the TiO2 center dot xH(2)O nanoparticles is related to the high surface area, large pore volume, and the presence of high affinity surface hydroxyl groups.
