dc.description.abstractThree activated carbon coated titanium dioxide composites are evaluated as adsorbents for the removal of three pharmaceutical compounds: clofibric, gallic and salicylic acids from aqueous solutions. These composite materials are characterized by several techniques as SEM, FT-IR, TGA and point of zero charge determination. The adsorption mechanism of acids was investigated and compared to the adsorption on the virgin carbon. The analysis of adsorption isotherms and kinetic properties reveals that the addition of TiO2 increased the adsorption capacities of the initial material. The adsorption kinetics has been studied in terms of pseudo-first and pseudo-second order kinetic models, and the Freundlich, Langmuir, Temkin, Tôth and Sips isotherms models have also been applied to the equilibrium adsorption data. The analysis of results indicated that the adsorption of acids on the activated carbon-titanium dioxide composites is well described by the pseudo-first order kinetic model and the Sips isotherm equation fitted the sorption experimental results better than other models.en
