Abstract Water contamination by effluent from industrial plants has been seriously considered as a global problem. Among the various sources of water pollution, the heavy metal ions dissolved in water are harmful and toxic to living beings. Therefore, to remove the heavy metals from water, various methods have been applied. Among the methods, the adsorption has been highlighted owing to ease of high efficiency and low cost. In this study, the removal behaviors of various heavy metals in water, such as chromium, selenium, manganese, and zinc, were investigated using commercial titania materials with different porosity and surface properties. No specific differences in crystal structure and morphology of the titania materials investigated by X-ray diffraction and scanning electron microscopy were confirmed. The porosity of the titania materials, such as specific surface area, pore volume, and pore size distribution, was elucidated from N2 adsorption-desorption isotherms. Zeta potential of the materials was measured to verify surface charge of the titania materials with different properties. The titania materials what we investigated have different mesopore volumes, pore sizes, and surface charges. It was found that the porosity and surface characteristics were a key point for the removal of heavy metals from water.
