title: Characteristics of phosphorus adsorption for a titanium mesostructure synthesized with various surfactants.
abstract: Eutrophication due to excessive phosphorus in water has been considered one of the most important environmental problems. In this study, a titanium mesostructure, prepared with different surfactant templates, was tested to confirm its applicability as an adsorbent for the removal of phosphorus and to evaluate the phosphorus removal efficiency. An X-ray diffraction analysis, the phosphorus adsorption isotherm and a kinetic test were performed on the titanium mesostructure synthesized with various molar ratios of base material to surfactant and different surfactant templates. It was revealed that the mesostructure synthesized with the molar ratio of 1.00/0.25 was the most uniformly and clearly formed and had the maximum adsorption capacity.
