Abstract

Surface modification of TiO₂ particles with specific chelating agents that may enhance both TiO₂ redox particles and adsorption of nitroaromatic compounds for selective, photocatalytic removal of nitroaromatics (nitrobenzene (NB), 2,4-dinitrotoluene, and 2,4,6-trinitrotoluene) from waste streams was studied. The NB adsorption and photodecomposition in the presence of phenol (Ph) over bare and arginine-modified nanocrystalline TiO₂ was presented. The presence of Ph increased the destruction of NB over arginine-modifed TiO₂, while in unmodified TiO₂ colloids NB conversion remained low. Ph photodecomposed over bare TiO₂ while no changes in Ph concentration were found for the arginine-modified colloid upon illumination.
