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.
