Highly efficient removal of thallium(I) by facilely fabricated amorphous titanium dioxide from water and wastewater.

ABSTRACT: In this study, amorphous hydrous titanium dioxide was synthesized by a facile precipitation method at room temperature, aiming to effectively remove thallium(I) from water. The titanium dioxide prepared using ammonia as precipitant (TiO₂^I) is more effective for thallium(I) uptake than the one synthesized with sodium hydroxide (TiO₂^II). The TiO₂ obtained particles are amorphous, aggregates of many nanoparticles and irregular in shape. The thallium(I) uptake increases with the rise of solution pH value. Under neutral pH conditions, the maximal thallium(I) adsorption capacities of TiO₂^I and TiO₂^II are 302.6 and 230.3 mg/g, respectively, outperforming most of the reported adsorbents. The amorphou
