| Outline of Final Research Achievements |
The purpose of this study is to apply TiO2 with the high active adsorption site to take up bisphenol A (BPA) in an aqueous solution. The mesoporous TiO2 beads with the surface area of 93.7 m2/g was prepared via a combined sol-gel self-assembly and solvothermal processes. The TiO2 beads could take up a little amount of BPA from an aqueous solution, and the Freundlich model is more suitable than the Langmuir model, describing the multilayer adsorption by heterogeneous surface energies. The uptake capacity of TiO2 beads modified with catechol was much higher than that of TiO2 beads. This is attributed to the hydrophobic interactions between the aromatic rings of BPA and catechol.
On the other hand, the uptake of nonionic aromatic compounds by Cu-Al layered double hydroxide modified with aromatic anion is expressed by Langmuir model, suggesting the monolayer adsorption.
