TiO2 solids of different grain size have been prepared by micelle-mediated hydrolysis and a solvothermal method, and characterized by SEM microscopy and N2 adsorption. The effect of the BET surface area/pore volume and the grain size of the solids on the U(VI) adsorption has been investigated by batch-type experiments and evaluated by correlating the textural parameters with the corresponding Kd values, which have been found to vary between 450 and 8600 ml g−1. The adsorption of U(VI) by TiO2 is well described by the Freundlich isotherm model and both, the BET surface/pore volume and grain size determine the adsorption efficacy.
