Abstract

Hexagonal sheet-like mesoporous titanium phosphate was synthesized by a facile hydrothermal method at 150 degrees C for a shorter duration of time (2 h) in the absence of any organic templates. The products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-vis spectroscopy, thermogravimetry (TG), N-2 adsorption-desorption, field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM). The performance of the hexagonal sheet-like particles for the removal of Pb(II) ions from water was evaluated. The adsorption data was interpreted with Langmuir and Freundlich models. The effect of contact time, adsorbate concentration, pH of the solution, temperature of the solution and adsorbent concentration on the adsorption capacity of the products was investigated. The prepared hexagonal sheet-like titanium phosphate showed maximum adsorption capacities up to 1073 mg g(-1), a higher value than those of previously reported phosphate compounds.
